calculateHg

Description

This function calculates Hedges g and Hedges g adjusted given the basic experimental statistics - the mean values for participants, number of observations (participants), and standard deviation in both the control group and the treatment group. . Hence, the function assumes the data is held as summary statistics including the control group mean, standard deviation and sample size and equivalent values for treatment group

Usage

calculateHg(Mc, Mt, Nc, Nt, SDc, SDt)

Arguments

Mc	is a vector containing the mean value of the control group for each experiment.
Mt	is a vector containing the mean value of the treatment group for each experiment.
Nc	is a vector containing the the number of observations (participants) in the control group for each experiment.
Nt	is a vector of the number of observations (participants) in the treatment group for each experiment.
SDc	is a vector of the standard deviations of the control group for each experiment.
SDt	is a vector of the standard deviations of the the treatment group for each experiment.

Value

data frame composed of Hedges' g and Hedges' g adjusted effect sizes
