Calculate Equally Spaced Differences

Description

This function calculates the equally spaced differences between means in a one-way ANOVA setup. It is based on the formula presented in Vanbrabant et al. (2015) for calculating differences between means, d.

Usage

d_eq_spaced(k, f)

Arguments

k	An integer representing the number of groups (k = 3, ..., 8).
f	A numeric value representing the effect size (f = 0.10, 0.15, 0.20, 0.25, 0.30, 0.40). Typical values represent small (0.10), medium (0.25), and large (0.40) effects.

Value

A numeric value representing the equally spaced difference, d, based on the number of groups (k) and the effect size (f).
