Document Summary
Corrects the error by multiplying significance value with 3 (for 3 independent variables) You can also divide alpha by 3 and compare to the original p-values. If lsd table: conduct bonferroni correction (because lsd = uncorrected table) Eta^2: between groups ss / total sum of squares proportion of total variation explained by the experimental factor. It"s a measure of effect size important because a significant effect is not necessarily a meaningful effect. Cohen"s d is also a measure of effect size. The 2 descriptives that demonstrate whether we are dealing with a normal distribution. Confidence interval skewness: plausible values of population level of the skewness. Confidence interval kurtosis: plausible values at population level of kurtosis. 0 kurtosis = normally distributed as 0 is part of the interval, we can assume that the population is population has normal kurtosis. Erases the outliers (or 2,5% of the scores on each side probably) and computes new mean: check the range of all numbers.
