Whenever the F-ratio is near 1.00, it means that:

Whenever the F-ratio is near 1.00, it means that:
 
  a. a mistake has been made in the computation.
  b. there are large systematic 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.

Question 2

If between-groups variance is large, then we have likely observed:
 
  a. experimenter effects.
  b. an effect of the dependent variable.
  c. enough samples.
  d. an effect of the independent variable.

Question 3

If within-groups variance is large, then we have observed:
 
  a. experimenter effects.
  b. an effect of the dependent variable.
  c. a large amount of error variance.
  d. an effect of the independent variable.
