This part provides an introduction to data cleaning. When data is really messy, data cleaning can be a challenging task. We provide some approaches that however, will not include or solve all issues during data cleaning.

7.1 Why data cleaning?

The validity of results of statistical data analyses depends on the quality of the data which in turn depends on several factors such as:

  • sampling (number of cases, representativeness, etc.)
  • research design
  • quality of the survey instrument
  • operationalization
  • data cleaning & data preparation

7.2 What is data cleaning?

Data cleaning (or data cleansing) is the process of identifying and correcting errors, inconsistencies, and inaccuracies in the data. It is always the first step after data entry or data transfer from external sources.

The steps of data cleaning vary depending on the type and quality of data. The following steps can be seen as a general outline:

  1. Understand the structure of the data (set) → Codebook should help
  2. Remove duplicate observations
  3. Handling missing data
  4. Plausibility checks (aka data validation)

7.3 How to clean data?

Depending on how much data cleaning is needed, it is recommended to clean data in a sequential way (We like it neat!). This means after we succeed with one step of data cleaning, we save the respective R- or Quarto script and the data set with an appropriate description (see Figure 7.1).

Figure 7.1: Example of sequential way of working with data

The sequential procedure is also exemplified in the next section Remove duplicate observations.

Important

When cleaning a data set, you should NEVER(!) replace the raw data with processed data (i.e., overwrite the raw data file). The manipulated data should be assigned to a new object and thereafter MUST BE saved as a new file!

The raw data should also be a read-only file (i.e., right click on the file > Properties > Attributes > Read-only).

Because it is also crucial to document the data cleaning process (i.e., to reconstruct all steps), we also recommend to use Quarto documents because of the increased readability.

7.4 Remove duplicate observations

Duplicate observations are identified via the id and variable values (i.e., response patterns). In Table 7.1 there are 3 different scenarios depicted that are problematic.

Table 7.1: Overview of duplicate observations scenarios
Scenario Action
Same id variable value, and same variable values (response pattern) delete one observation
Same id variable value, but different variable values (response pattern) check data (i.e., questionnaires)
Different id variable values, but same variable values (response pattern) complicated, it is possible, but check data (i.e., questionnaires, especially open fields)

Identification (ID) variables are eminent when working on projects that contain several sources (e.g., different questionnaires), or span across multiple years (e.g., longitudinal studies) and must be planned before the data collection.

ID variables should be …

  • uniquely identifying → no duplicates

  • fully identifying → all observations have an ID variable value

  • constant throughout the duration of projects → observations do not have different IDs in a other datasets

  • anonymous

For more see here: https://dimewiki.worldbank.org/ID_Variable_Properties

The procedure is as follows:

  1. Import data → we use the data set from below: exDatID

  2. Find duplicate observations

  3. Exclude real (!) duplicates (but consult your supervisors!)

  4. Save data set to a new file

Generate some duplicate observations.

!! Do not do this with real data !! !! Do not do this with real data !! !! Do not do this with real data !!

The example data set exDat does not contain any duplicate observations. Hence, we have to create them. This is done with the base::rbind function (i.e., adding the first five rows of the example data set (i.e., exDat[1:5]) to the same data set).

Show/hide code
exDatID <- rbind(exDat,exDat[1:5,])
exDatID[c(751, 752),"id"] <- c(751, 752)
exDatID[6,"id"] <- 7
set.seed(999)
exDatID$comment <- c("Hi, i like playing video games.",
                     "Hello, I am strong like Hulk.",
                     "i like apples!", "i like avocados!", "bye...",
                     sample(c("no", "nope", "nopeee", "no!", "no...", "..."), 745, replace = TRUE),
                     "Hi, i like playing video games.",
                     "Hello, I am strong like Hulk.",
                     "i like apples!", "i like avocados!", "bye...")

nrow(exDatID)
[1] 755

!! Do not do this with real data !! !! Do not do this with real data !! !! Do not do this with real data !!

For the exercise below, write the exDatID data set to your project folder.

Show/hide code
getwd()
write.csv2(x = exDatID,
           file = "exDatID.csv",
           row.names = FALSE)

How to find and remove duplicate observations via the id and variable values? In the following there is a base R and a dplyr (Wickham, François, et al., 2023) solution shown. Both approaches use the duplicated() function which requires a vector, a data frame or an array as input x. The output is logical vector (TRUE/FALSE) of the same length as x.

  1. Open a new R- or Quarto-script (i.e., File > New File) and provide an meaningful name.

  2. Import the exDatID.csv data set (which was generated above)

Show/hide code
exDatID <- read.csv2(file = "exDatID.csv",
                     header = TRUE)
  1. Go through the following steps. Choose either between the base R or the dplyr approach.

  2. Save the cleaned data set (i.e., without the duplicates) with a meaningful name that also matches the name of the script.

Show/hide code
getwd()
write.csv2(x = exDatIDclean,
           file = "studyname-01-01-data-cleaned-remDup.csv",
           row.names = FALSE)
  1. Identify the duplicate id values: Use the ifelse function to transform the returned logical vector of the duplicated function to a character variable and then it as a new variable1 (here: dupID) to the data set.
exDatID$dupID <- duplicated(exDatID$id)
table(exDatID$dupID)

FALSE  TRUE 
  751     4 
  1. Identify with the which function which id values are duplicated.
whichID <- exDatID[which(exDatID$dupID == TRUE), "id"]
whichID
[1] 7 3 4 5
  1. Select only the the rows with duplicated id values (unlist the whichID object).
dupIDs <- tibble::as_tibble( exDatID[exDatID$id %in% unlist(whichID),] )
  1. Show the (ordered) data set.
dupIDs[order(dupIDs$id),]
# A tibble: 8 × 11
   msc1  msc2  msc3  msc4   age   sex   edu fLang     id comment          dupID
  <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl> <chr>  <dbl> <chr>            <lgl>
1     2     2     3     3 12.8      0     0 german     3 i like apples!   FALSE
2     2     2     3     3 12.8      0     0 german     3 i like apples!   TRUE 
3     2     2     3     2 10.6      0     0 german     4 i like avocados! FALSE
4     2     2     3     2 10.6      0     0 german     4 i like avocados! TRUE 
5     3     2     2     2  9.89     1     0 german     5 bye...           FALSE
6     3     2     2     2  9.89     1     0 german     5 bye...           TRUE 
7     3     3     3     2 10.4      0     0 german     7 nopeee           FALSE
8     4     4     1     2 10.9      1     0 german     7 no!              TRUE 

What do we see? 4 duplicated id values: 3, 4, 5, 7 were identified, but only 3, 4, and 5 are “real” duplicate observations. In a real data set, this would be probably a input error during data entry. Hence, it would be necessary to check the questionnaires. We know that it was a mistake, because we created the error (see above). Thus, we can reverse it without further ado. But be careful that you select the right observation.

exDatIDclean <- exDatID
exDatIDclean[exDatIDclean$id == 7 & exDatIDclean$comment == "nopeee","id"] <- 6
exDatIDclean[exDatIDclean$id == 7,"dupID"] <- " "

The observations with the id values 3, 4, and 5 can be deleted. Therefore, we can use the subset function that requires the input x which can be matrices, data frames or vectors (including lists). In the subsetargument you can state logical expression indicating elements or rows to keep (here: != dup).

exDatIDclean <- subset(x = exDatIDclean,
                       subset = dupID != TRUE)

751 Hi, i like playing video games. FALSE
752   Hello, I am strong like Hulk. FALSE

Note that there are still 2 duplicate observations left. Nevertheless, we can delete the variable dupID and clean our environment with the base::rm function:

exDatIDclean$dupID <- NULL
rm(whichID, dupIDs)

What to do with the other 2 duplicate observation? We need to repeat the procedure. This time we do not examine the id values (i.e., actually we need to exclude this variable), but the response pattern. This is done as follows:

dupResp <- exDatIDclean[duplicated(exDatIDclean[, -which(names(exDatIDclean) == "id")]) |
                        duplicated(exDatIDclean[, -which(names(exDatIDclean) == "id")],
                                   fromLast = TRUE), ]

751 Hi, i like playing video games.
752   Hello, I am strong like Hulk.

Recall, the real duplicates are the observations with the id values 751 and 752, but we identified 4 more observations with non-unique patters…this needs careful investigation.

You may also want to check the base::unique function.

nrow(
  unique(exDatIDclean[, -which(names(exDatIDclean) == "id")])
  )
[1] 748
unique(exDatIDclean[, -which(names(exDatIDclean) == "id")])

The base::unique function eliminated 2 additional observations that are no real duplicates…Hence, it is important to carefully applying the base::unique function and checking that it does not eliminate different observations with the same response pattern (only real duplicates)!

In the first step, we identify the duplicated id values with the base::duplicated function and adding a new column (dupID) using the dplyr::mutate function to the data set. Then we filter (using the dplyr::filter()) observations based on the returned TRUE values of the base::duplicated function Lastly, we select the id column (using dplyr::select) and base::unlist and base::unname it.

  dplyr::mutate(dupID = duplicated(id)) |>
  dplyr::filter(dupID == TRUE) |>
  dplyr::select(id) |>
  unlist() |>
  unname()

751 Hi, i like playing video games.
752   Hello, I am strong like Hulk.

Similar to the base::unique function, the dplyr package provides a function dplyr::distinct() which can be used to keep only unique rows.

nrow(
  dplyr::distinct(exDatIDclean[, -which(names(exDatIDclean) == "id")]) 
)
[1] 748
dplyr::distinct(exDatIDclean[, -which(names(exDatIDclean) == "id")])

The dplyr::distinct function eliminated 2 additional observations that are no real duplicates…Hence, it is important to carefully applying the dplyr::distinct function and checking that it does not eliminate different observations with the same response pattern (only real duplicates)!

7.5 Handling missing data

Missing data is a common problem in most behavioral science research (Enders, 2010, 2023; Schafer & Graham, 2002). Especially, in questionnaire surveys it is unavoidable that values are missing because a field of the questionnaire was not filled in or a person dropped out of the study. Therefore, it is essential to examine the data with regard to missing data. By missing values, we refer to cells that could have a value, but whose value is not available (see section on Data Types in the Introduction to R & RStudio part).

The procedure encompasses 3 2 steps:

  1. Define missing values
  2. Examine missing values
  3. (Omit missing values → usually not recommended)

7.5.1 Define missing values

In other statistical software programs (e.g., SPSS) or in study planning, missing values are often defined as numeric values (e.g., -9, -88 or -99)2 or as empty characters/strings (i.e., "" or " "). In R, missing values are represented by the symbol NA (not available). This means, the first step is to ensure that all missing values are declared as NA in the data set.

Assign -99 & -88 values

!! Do not do this with real data !! !! Do not do this with real data !! !! Do not do this with real data !!

The example data set exDat does also not contain any missing values that are not NA values. Hence, we have to create them. With the following code, we assign the values -99 to the first 5 rows of the variable age and -88 to the first 4 rows of the variables sex and edu (and store it in a new data set exDatMis).

exDatMis <- exDat
exDatMis[1:5, "age"] <- -99
exDatMis[1:4,c("sex", "edu")] <- -88
head(exDatMis, 6)
  msc1 msc2 msc3 msc4       age sex edu  fLang id
1    2    3    2    2 -99.00000 -88 -88 german  1
2    3    2    1    1 -99.00000 -88 -88 german  2
3    2    2    3    3 -99.00000 -88 -88 german  3
4    2    2    3    2 -99.00000 -88 -88 german  4
5    3    2    2    2 -99.00000   1   0 german  5
6    3    3    3    2  10.44685   0   0 german  6

!! Do not do this with real data !! !! Do not do this with real data !! !! Do not do this with real data !!

To demonstrate the effect, we calculate the mean of the variable age in the exDat and exDatMis data set:

mean(exDat$age, na.rm = T)
mean(exDatMis$age, na.rm = T)
[1] 10.03468
[1] 9.218226

To set the numeric values of -99 or -88 to NA, we may use one of the following two approaches:

For a single variable:

exDatMis$age[exDatMis$age == -99] <- NA

For multiple variables:

colToNa <- c("sex", "edu")
exDatMis[colToNa][exDatMis[colToNa] == -88] <- NA

For the whole data set:

exDatMis[exDatMis == -99] <- NA

The na_if() function from the dplyr package (Wickham, François, et al., 2023) is designed to to convert (specific) values to NA.

For a single variable:

exDatMis$age <- dplyr::na_if(exDatMis$age, -99)

For multiple variables:

colToNa <- c("sex", "edu")
exDatMis <- exDatMis |>
  dplyr::mutate(dplyr::across(colToNa, na_if, y = -88)) 

For the whole data set:

exDatMis <- exDatMis |>
  dplyr::mutate(dplyr::across(colnames(exDatMis), na_if, y = -88))

But note that na_if() is meant for use with vectors rather than entire data frames.

7.5.2 Examine missing values

The is.na function indicates which elements are missing. It requires an input x that can be e.g., a vector, data.frame or list. The values that are returned depend on the input. For example, when you pass a vector to the function, it returns a logical vector of the same length as its argument x, containing TRUE for those elements marked NA or, for numeric or complex vectors, NaN, and FALSE otherwise.

is.na(
  c(1, NA, "hello", NaN, " ")
  )
[1] FALSE  TRUE FALSE FALSE FALSE

In the following, we show how the is.na function may be applied to variables within a data set. To count the missing values (or to be more specific the returned TRUE values), we use the sum and colSums functions.

The summary() function returns beside some descriptive statistics (e.g., minimum, maximum, mean, …), also the amount of NAs of each variable of the given data set.

Exercise: Count the missing values!

7.5.3 Omit missing values

Although omitting or deleting missing values is a common practice, this is not recommended to deal with missing data and should–in most scenarios–be avoided altogether (Schafer & Graham, 2002). Two “state-of-the-art” missing data methods are maximum likelihood estimation (e.g., implemented in the lavaan package, see Rosseel et al., 2023) and multiple imputation (e.g., implemented in the mice package, see van Buuren & Groothuis-Oudshoorn, 2021; for good introductions to this topic, see Enders, 2010).

Documentation of missing data

For the sake of documentation it is important to report the percentage of missing data of the variables in the data set.

Nevertheless, if you would like to omit missing values anyway, there are several functions to do this in R. Also, it is important to note that ignoring or omitting missing values are often the default options in R.

For example, by negating the is.na function (i.e., !is.na), those rows that do not contain NAs on a variable or data set are kept.

For a single variable:

exDat[!is.na(exDat$age), ]
    msc1 msc2 msc3 msc4       age sex edu   fLang  id

7.6 Plausibility checks

So-called plausibility checks are performed in order to detect:

  • structural errors → e.g., the range of a lickert scale is from 1 to 4, but the value 5 occurs
  • theoretical inconsistencies → e.g., 30 years of age in sample of primary students
  • (statistical) outliers → see Excursus on outlier in the following

According to wikipedia, outliers can be defined as a data point that differs significantly from other observations.

Outliers may occur due to different reasons:

  • data entry errors
  • measurement error
  • “true” extreme values

Outliers must be detected, because they may introduce bias into parameter estimates of statistical models and hence, compromise the validity of the results.

Different ways of detecting outliers:

  • Z-score (e.g., above or below \(3SD\))
  • Visualization (e.g., box plots, histograms, or scatter plot)
  • Mahalanobis distance

Plausibility checks can be performed both analytically and graphically. Graphics can be created with base R (R Core Team, 2023), or packages such as lattice (Sarkar, 2021) and ggplot2 (Wickham, Chang, et al., 2023) that are specifically designed for data visualization. Although base R graphics are useful (especially for creating simple plots), the ggplot2 package is more powerful and flexible for creating complex visualizations. You may load the package via:

Note that ggplot2 package (Wickham, Chang, et al., 2023) is part of the tidyverse and nicely works with the dplyr package (Wickham, François, et al., 2023). For an introduction see the tidyverse documentation of ggplot2.

To perform plausibility checks analytically, the base::range function is a useful starting point to quickly examine the minimum and maximum of variables that are no characters/string variables (i.e., !is.character).

  1. Identify all non-character variables using the !is.character function within a base::lapply loop. Because base::lapply returns a list, we need to base::unlist the output to get a logical vector.
nChrV <- unlist(lapply(exDatMis,
                         function(x) !is.character(x)),
                use.names = FALSE)
#class(nChrV)
  1. Then we can apply the base::range function to the respective variable within the exDatMis.

The base::apply function is designed to apply functions (e.g., base::range) over array margins (e.g., rows or columns) and needs the following arguments (copied from the function description):

  • X: an array, including a matrix.
  • MARGIN: a vector giving the subscripts which the function will be applied over. E.g., for a matrix 1 indicates rows, 2 indicates columns, c(1, 2) indicates rows and columns. Where X has named dimnames, it can be a character vector selecting dimension names.
  • FUN: the function to be applied: see ‘Details’.
apply(exDatMis[,nChrV],
      2,
      FUN = range, na.rm=TRUE)
     msc1 msc2 msc3 msc4      age sex edu  id
[1,]    1    1    1    1  5.43976   0   0   1
[2,]    4    4    4    4 30.00000   1   4 750

In the dplyr package we first use the select function (i.e., to select the variables) in combination with where function to identify all non-character variables by stating !is.character. Then applying the base::range function on very variable in the data set.

exDatMis |>
  dplyr::select(
    dplyr::where(~!is.character(.))
    ) |>
  dplyr::summarise_all("range", na.rm = TRUE)

  msc1 msc2 msc3 msc4      age sex edu  id
1    1    1    1    1  5.43976   0   0   1
2    4    4    4    4 30.00000   1   4 750
  1. Identify the observation with age == 30, using the base::which function.
exDat[which(exDat$age == 30),c("id", "age")]
     id age
600 600  30
  1. Set the value 30 of the variable age to NA.
exDat[which(exDat$age == 30),"age"] <- NA

7.6.1 Categorical variables

7.6.1.1 Frequencies/Counts

To do further plausibility checks on categorical variables, we may examine counts (at each combination) of factor levels (e.g., examine extreme responses in one category).

The base::table function builds a contingency table of the counts at each combination of factor levels.

Note that by default, NAs are not included in the base::table function. To include NAs, we need to change the useNA argument to "ifany" (only if the count is positive) or "always" (even for zero counts).

table(exDatMis$edu, useNA = "always")

   0    1    2    3    4 <NA> 
  46  100  150  200  250    4 

The dplyr approach is using the count function that counts the unique values of one or more variables.

exDatMis |>
  dplyr::count(edu) 
  edu   n
1   0  46
2   1 100
3   2 150
4   3 200
5   4 250
6  NA   4

7.6.1.2 Graphical inspection using bar charts

Bar charts are one way of graphically checking the plausibility of discrete variables.

barplot(
  height = table(exDat$edu, useNA = "always"),
  names.arg = c(0:4, "NA"),
  #main = "Education in example data set (barplot)", # plot title
  xlab = "edu", # x-axis label
  ylab = "Count",  # y-axis label
  ylim = c(0, 300) # y-axis range
  )

Figure 7.2: Frequencies of the variable education in the example data set (barplot)

exDat |>
  dplyr::count(edu) |>
  ggplot(aes(x = edu, y = n)) +
  geom_bar(stat = "identity", color = "black", fill = "lightgrey") +
  geom_text(aes(label=paste("n = ", n)), vjust=1.6, color="black", size=3.5)+
  labs(x = "edu", y = "Count") +
  theme_classic()

7.6.2 Continuous variables

Continuous variables are checked by examining the distribution of the variables. It is reasonable to start checking the range (i.e., minimum & maximum) of the variable (using the base::range function, see e.g., above).

7.6.2.1 Distribution parameters/measures

Furthermore, the following Distribution parameters/measures might be informative:

In the following, we show how to examine the skewness and kurtosis. The calculation of the other parameters is introduced in the section on Descriptive statistics and item analysis.

moments::skewness(exDat$age,
                  na.rm = T)
[1] -0.06354551
moments::kurtosis(exDat$age,
                  na.rm = T)
[1] 3.085664

What are the cutoffs for skewness and kurtosis? It depends on the specific context…

  • Skewness: 0 (perfect symmetry) → cutoff: 1-2
    • \(> 0\): right-skewed distributions
    • \(< 0\): left-skewed distributions
  • Kurtosis: 3 (perfect normal distribution) → cutoff: 6-7
    • \(> 3\): more peaked distribution
    • \(< 3\): a flatter distribution

7.6.2.2 Graphical inspection using histogram

Histograms are graphical representations of frequency (or relative frequency) distributions of variables and are used to visualize the shape of a distribution.

hist(exDat$age,
     main = "Age in example data set",
     breaks = 20,
     xlim = c(min(round(exDat$age), na.rm = T) - 1,
              max(round(exDat$age), na.rm = T) + 1),
     ylim = c(0, 100)
     )

Figure 7.4: Frequency distribution of age in example data set

ggplot(data = exDat, #na.omit
       aes(x = age)) +
  geom_histogram(bins = 100,
                 binwidth = .5,
                 color = "black",
                 fill = "white") +
  geom_vline(data = exDat, aes(xintercept = mean(age, na.rm = T)),
             linetype="dashed",
             color="red") +
  scale_x_continuous(limits = c(
    min(exDat$age,
        na.rm = T)-1,
    max(exDat$age,
        na.rm = T)+1)) +
  theme_minimal()

7.6.2.3 Graphical inspection using boxplots

Boxplots allow visualization of the most important robust measures of location and dispersion.

boxplot(exDat$age,
        #main = "plot title",  
        xlab = "Variables", # x-axis label
        ylab = "Range" # y-axis label
        )

Figure 7.6: Boxplot of variable age in the example data set

ggplot(data = exDat, #na.omit
       aes(y = age, x = factor(0))) +
  geom_boxplot(width=.5, outlier.color = "red") +
  #geom_jitter(width = .25, color = "grey", alpha = .2) +
  scale_x_discrete(breaks = NULL) +
  xlab(NULL) +
  theme_bw()
