Matched Subjects Design Psychology homework help

Review the “Matched-Subjects Design” document attached and follow the instructions listed in the document.

Working with your group members, complete the design experiment.

After completing the exercise, have a scholarly discussion around the following questions in your CLC thread:

  1. Advantages for each technique. Provide at least two.
  2. Disadvantages for each technique. Provide at least two.
  3. Discuss the criteria used to determine the appropriateness of random assignment versus matching techniques.

As the group comes to a consensus for each question, choose a recorder to record the consensus in a word document to be submitted to your instructor.

Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

List the points to convey your consensus; then through scholarly research, explain under what conditions these different grouping techniques are necessary.

Matched-Subjects Design

1) Separate the 40 participants listed below into two groups of 20, in which each group has an equal number of men and women (10 M, 10 F each). Name the first group A and the second group B.

2) Match 1: Random Assignment

a. Use a random numbers table to accomplish the first match, utilizing Group A and Group B. Please search for a random numbers table on the internet or use the one in the back of the textbook to successfully complete this section of the assignment.

b. Start anywhere in the table and proceed in any direction that you like.

c. Odd numbers put the subjects in Group A; even numbers in Group B.

d. When one group is filled, the rest go into the other group.

3) Match 2: Range Matching 1

a. Return to the original Group A and Group B lists.

b. Separate the participants into two groups by gender using range matching.

c. Match as many pairs of female participants as possible: find a match and randomly assign one to the Group A, and the other to the Group B.

d. Next, do the same for the male participants.

4) Match 3: Range Matching 2

a. Return to the original Group A and Group B lists.

b. Match participants by two variables: gender AND weight.

c. Decide on your acceptable ranges in advance (i.e., within 5 pounds for females and 10 pounds for males).

d. Find a match and randomly assign one to the Group A, and the other to the Group B.

e. Form a Group C for individuals who do not match.

5) Match 4: Range Matching 3

a. Return to the original Group A and Group B lists.

b. Match the participants on all three variables (gender, weight, and height).

c. Decide on your acceptable ranges in advance (i.e., within 5 pounds for females and 10 pounds for males).

d. Find a match and randomly assign one to Group A, and the other to Group B.

e. Form a Group C for individuals who do not match.

6) Match 5: Rank Order Matching

a. Using the original list of 40 participants, split the participants by gender (all male group and all female group).

b. Then rank groups by weight OR height, using rank-ordered matching (i.e., heaviest to lightest or tallest to shortest).

c. Find a match and randomly assign one to the Group A, and the other to the Group B.

40 Participants to be matched:

Name Gender Weight (lbs.) Height (in.)
