I need help with a Statistics question. All explanations and answers will be used to help me learn.
Homework 8 focuses on the application of concepts addressed in Exercises 19 and 35.
This homework uses data from a randomized prospective study by LePage and colleagues (2017). A sample of 111 veterans with a history of homelessness and mental illness were randomly assigned to either an experimental treatment condition involving a specialized vocational program, or treatment as usual services at a veterans affairs health center. One of the study outcomes was obtaining stable employment post-treatment (in other words, the rate of stable employment).
The two variables in this example are dichotomous: Group (Experimental Program versus Treatment as Usual {TAU}) and having obtaining stable employment post-treatment (yes/no).
These data are presented in HW8.sav. The null hypothesis is “There is no difference between the experimental and TAU veterans on achieving stable employment post-treatment.”
Questions to be answered in word Doc
Open in SPSS. Use the dataset to answer the following questions.
The study data are presented in HW8.sav. The contingency table is below:
|
Stable |
No Stable |
|
|
Experimental Group |
10 |
17 |
|
Treatment As Usual (TAU) |
7 |
77 |
- Compute the chi-square. List the numerator.
- List the denominator.
- Using the numbers in the contingency table, calculate the percentage of veterans in the Experimental Group who achieved stable employment.
- Using the numbers in the contingency table, calculate the percentage of veterans in the TAU Group who achieved stable employment.
- Write your interpretation of the results, as you would in an APA-formatted journal.
