A nonparametric equivalent of the independent t-test
mann_whitney(
data = NULL,
iv_name = NULL,
dv_name = NULL,
iv_level_order = NULL,
sigfigs = 3
)
data |
a data object (a data frame or a data.table) |
iv_name |
name of the independent variable (grouping variable) |
dv_name |
name of the dependent variable (measure variable of interest) |
iv_level_order |
order of levels in the independent
variable. By default, it will be set as levels of the
independent variable ordered using R's base function |
sigfigs |
number of significant digits to round to |
the output will be a data.table object with all pairwise Mann-Whitney test results
