Ques. 2

In a nonrandomized control group, pretest-posttest design, the recommended procedure for analyzing test results is a(n)
 
  a. t-test of the difference between pretest and posttest means for both the experimental and the control group.
  b. four-way analysis of variance.
  c. analysis of covariance, in which the posttest means are compared using the pretest means as the covariate.
  d. analysis of variance of the mean pretest-posttest change for the experimental and control groups.

Ques. 7

The most meaningful way to consider test validity is
 
  a. across parallel forms. c. for a specific purpose.
  b. as a subtype of reliability. d. in terms of errors of measurement.

Ques. 8

A research study has a design with two groups receiving a pretest, one of which receives treatment and two groups who are not pretested, one of which receives treatment. This design is called a

  c. be inconsistent measures of the important aspects of the construct.
  d. a and b
