Alternative name for static-group comparison design?

A

Static groups

Non-equivalent control group design

35
Q

indicates that the two groups being compared are already formed

A

Dashed line (—–)

36
Q

Pretest is given to both groups and a “gain or change” is determined by getting the sum of scores

A

Static-group pretest-posttest design

37
Q

Essential ingredient of a true experimental design

A

Randomly assigned to treatment groups

38
Q

Involves two groups, both of which are formed by random assignment

A

39
Q

Best design in experimental study provided there are atleast 40 subj in each group

A

Randomized Posttest-Only Control Group Design

40
Q

One group receives the experimental treatment while other does not; both groups are prettested

41
Q

Differs from previous designs solely in the use of pretest.

A
