What is the primary advantage of a repeated-measures design over an independent-measures design?
The primary strengths of the repeated measures design is that it makes an experiment more efficient and helps keep the variability low. This helps to keep the validity of the results higher, while still allowing for smaller than usual subject groups. twas on wikipedia so not so reliable
Uses of ANOVA?
The ANOVA test means ANalysis of Varience and it is used to test for difference among group means. ---- That is the amount of variability between the means of the groups compared to the amount of variability among the individual scores of each group. Varience between groups versus varience within groups. Hope this helps...Natalie
