Resumo: | Sample sizes required for the detection of significant differences among experimental treatments in scientific research are presented. An approach based on the magnitude of the coefficient of determination (R2) among treatments was used. The required sample sizes decrease with increase in R2. For detecting true differences with magnitudes of one standard deviation of the trait, the required sample size are 15 to 5 for R2 ranging from 5% to 70%.
