Q

What would happen if we were to increase the within-group variance for each condition of the independent variable?

A

The F statistic value would decrease and be less likely to prove significant.

Q

To what does the term ‘SSM’ refer?

A

To how much of the variance observed within a set of data can be explained by the difference between the means of each separate condition of the independent variable.

Q

How can the SSM be calculated?

A

By squaring the difference between the mean of each separate condition of the independent variable and the group mean, multiplying each of these values by the number of participants involved in each group, and adding each of these values together.

Q

To what does the term ‘SSR’ refer?
