 a. mean square for treatments. c. total sum of squares.
  b. mean square for error. d. None of these choices.

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
