Question 18)

Suppose we classify the participants into groups- those who are procrastinator and those who are not belongs to a within subjects design ( related measures design).

Reason:- In related measure design the we can use same individual and test them on two or more separate occasions in that case within subject design used.the same conditions used in this example so within subject design is used.

In ANOVA the first calculation of amount of variabilty between & within groups is termed as sum of squares.

In ANOVA total sum of squares is split up into various sum of squares i.e sum of squares between groups and within groups hence it is termed as sum of squares.
