The scatterplot suggests that the error term is heteroscedastic, with the smallest variance near age 7. The data are set out as follows: To find the 95% confidence interval above and below the mean we now have to find a multiple of the standard error.

Mathematically this formula can be written as: Hedges' g method of effect size: This method is the modified method of Cohen's d method. 8, and we compute a.
