Week 9 Assignment
For this assignment you will use the Week_09_Assignment_Data.csv file, which can be found on the Week 9 Assignment page in Canvas. This is a hypothetical dataset. Assume these data were collected from a representative sample of students from one large undergraduate-level psychology program.
The dataset includes the following variables:
· id : A unique nominal-level identification number assigned to each student
· admit_type : Classification of whether the student was admitted as a transfer student (trn) or first-year student (fyr). Transfer students are admitted with at least 18 transfer credits while first-year students are admitted with less than 18 transfer credits.
· program : Whether the student was enrolled in the applied behavior analysis (aba) program, general psychology program, or pre-counseling program.
Criteria:
· Conduct a chi-square test in JASP
· Explain how to check the assumptions of a chi-square test
· Interpret the statistical significance of a chi-square test
· Write a paragraph in APA style summarizing the results of your analysis
|
In JASP, conduct a chi-square test of independence to determine if there is evidence of a relationship between admit_type and program. Include the expected counts on your contingency table. Request Cramér’s V as a measure of effect size. |
|
[Include a screenshot of your JASP output here. Include the contingency table, chi-square tests table, and the table showing Cramér’s V.] |
|
Have both assumptions of the chi-square test of independence been met? Explain how you checked each assumption. |
|
|
|
At the .05 alpha level, is the test statistically significant? Explain how you determined this. |
|
|
|
Is there evidence of a relationship between admit_type and program in this population? Explain how you determined this. |
|
|
|
Write a paragraph that briefly summarizes the study and reports the results of the chi-square test in APA style. Most students will need between 40 and 60 words. |
