R Documentation

Mann-Whitney U Test (Also called Wilcoxon Rank-Sum Test)

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 `sort`.
`sigfigs`	number of significant digits to round to

the output will be a data.table object with all pairwise Mann-Whitney test results
