Chapters 8 and 9_Factorial Designs and Quasi-Experiments

Question 1

Factorial Design

Answer 1

An experimental design in which two or more independent variables (factors) are manipulated to observe their effects.

Question 2

2 × 2 Factorial Design

Answer 2

A design with two independent variables, each having two levels, creating four possible conditions (2 × 2 = 4).

Question 3

2 × 3 Factorial Design

Answer 3

A design with two independent variables, one with two levels and the other with three levels, creating six conditions.

Question 4

3 × 3 Factorial Design

Answer 4

A design with two independent variables, both having three levels, creating nine conditions (3 × 3 = 9).

Question 5

Main Effects

Answer 5

The separate effects of each independent variable in a factorial design, averaged across the levels of the other variables.

Question 6

Interaction Effects

Answer 6

Occur when the effect of one independent variable depends on the level of another independent variable.

Question 7

Quasi-Experiments

Answer 7

Studies that aim to evaluate interventions but lack random assignment to control and experimental groups.

Question 8

One-Group Posttest-Only Quasi-Experimental Design

Answer 8

A design where a single group is measured after receiving an intervention, without any pretest comparison.

Question 9

One-Group Pretest-Posttest Quasi-Experimental Design

Answer 9

A design where a single group is measured both before and after receiving an intervention.

Question 10

Non-Equivalent Groups Quasi-Experimental Design

Answer 10

A design where two or more groups are compared, but participants are not randomly assigned to groups.
