Single sample t-test
The single sample t-test tests the null hypothesis that the population mean is equal to a given number.
Independent groups t-test
This test is designed to compare the means of observations in the same column between two groups.
Paired t-test
A paired (or "dependent") t-test is used to compare the means of observations that are not independent of one another.
One-way ANOVA
The one-way analysis of variance (ANOVA) allows to test if any of several means are different from each other.
Cronbach Alpha
Computes the Cronbach Alpha for all numerical columns based on their variance.
Standardized Cronbach Alpha
Calculate the standardized Cronbach Alpha, a general measure for internal consistency of the data.
Rank Correlation
Computes correlation coefficients for pairs of columns, based on the sorting of its values only.
Statistics
Calculates statistic moments with their distributions as histograms and counts nominal values and their occurrences across all columns.
Crosstab
Creates a cross-tabulation (also referred as contingency table or cross-tab).
Value Counter
Counts the occurrences of values in a column
