In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator of the ratio is:
 a. mean square for treatments. c. total sum of squares.
  b. mean square for error. d. None of these choices.

Q. 2

If avoiding large errors is important, ____________________ should be used because it penalizes large deviations more heavily than does MAD.
 Fill in the blank(s) with correct word

Q. 3

In the one-way ANOVA where k is the number of treatments and n is the number of observations in all samples, the degrees of freedom for treatments is given by:
 a. n - k c. n - 1
  b. k - 1 d. n - k + 1

Q. 4

MAD averages the absolute differences between the actual and ____________________ values.
 Fill in the blank(s) with correct word

Q. 5

In the one-way ANOVA where there are k treatments and n observations, the degrees of freedom for the F-statistic are equal to, respectively:
 a. n and k. c. n - k and k - 1.
  b. k and n. d. k - 1 and n - k.
