sm_effsize: Cohen's d - effect size

Cohen's d - effect size

Description

Cohen's d is a measure of the effect size. It is often reported with p-values (ex. from a t-test or posthoc pairwise comparisons).

Usage

sm_effsize(group1, group2, absolute = TRUE)

Arguments

group1	Numeric vector containing data from one sample (i.e., group 1) that is to be compared with another group.
group2	Numeric vector containing data from another sample (i.e., group 2) that is to be compared with the former group.
absolute	If set TRUE, the function will print the absolute value of the effect size. If set FALSE, the function will print effect size of group2 - group1. For example, it will be positive if group2 has a larger mean than group 1.

Value

Returns a double vector that is the effect size between two samples.

Examples

library(smplot2)
group1 <- rnorm(10,0,1)
group2 <- rnorm(10,1,1)
sm_effsize(group1, group2)
