The larger the within-groups (error) variance, _____.

a. the more difficult it becomes to show the effects of experimental variance
b. the easier it becomes to show the effects of experimental variance
c. the more difficult it becomes to perform the F test
d. the easier it becomes to show a causal effect of the independent variable on the dependent variable

Question 2

a. a mistake has been made in the computation.
b. there are large error effects present.
c. the experimental manipulation probably had the predicted effects.
d. the between-groups variation is no larger than would be expected by chance alone and no larger than the within-groups variance.
