1. For a hypothesis test using the single-factor ANOVA formula:

The obtained overall F ratio = MS between treatments divided by MS within treatments.

Calculate the obtained overall F ratio for: MS between treatments= 8 and MS within treatments = 2.

Then describe the null hypothesis decision for = .05, df numerator: 3, and df denominator: 4.

(F Distribution Table is on pages 539 - 541.)

Reject the null hypothesis or Fail to reject the null hypothesis.

2. For the repeated-measures ANOVA analysis, denominator measures how much variance is expected if there are no systematic treatment effects and no individual differences contributing to the variability of scores. true/false

3. For single-factor ANOVA: The null hypothesis indicates that the treatment conditions have no effect on performance. true/false

4. In the F-ratio for repeated-measures ANOVA, variability due to individual differences is automatically eliminated from the numerator, and can be measured and removed from the denominator. true/false
