In our summary table we can see that MSbetween is greater than MSwithin, making F larger than 1, this fits what we would expect if H0 was false (i.e. if our independent variable really did have an effect). That large value of F, however, could just be due to random sampling error. find the probability of getting such a large value of F is H0 were true.

1. p=?

2. Compute the effect size of the independent variable. =?

3. Changing into a percent.

We can say that ___% of the variance in anxiety among the subjects can be accounted for by knowing which room the subject was in.
