Describe an example of the parts of the classical experimental design and three preexperimental designs.

Question

Quizplus · Accepted Answer

The Answer is An example of the parts of the classical experimental design includes the following:

1. Independent variable: This is the variable that is manipulated or changed by the researcher. For example, in a study on the effects of caffeine on memory, the independent variable would be the amount of caffeine consumed.

2. Dependent variable: This is the variable that is measured or observed to see if it is affected by the independent variable. In the caffeine and memory study, the dependent variable would be the participants' performance on a memory test.

3. Control group: This is a group of participants who do not receive the experimental treatment or intervention. In the caffeine and memory study, the control group would be given a placebo instead of caffeine.

4. Experimental group: This is the group of participants who receive the experimental treatment or intervention. In the caffeine and memory study, the experimental group would be given varying amounts of caffeine.

Three preexperimental designs include:

1. One-shot case study: This design involves a single group of participants who are exposed to a treatment or intervention, and then their behavior is observed. For example, a researcher might give a group of students a study skills workshop and then measure their academic performance.

2. One-group pretest-posttest design: In this design, a single group of participants is measured on a dependent variable before and after they receive a treatment or intervention. For instance, a researcher might measure participants' anxiety levels before and after they undergo a stress reduction program.

3. Static-group comparison: This design involves comparing the performance of two different groups on a dependent variable, with one group receiving the treatment or intervention and the other group not receiving it. For example, a researcher might compare the test scores of students who received a tutoring program with those who did not receive the program.
