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
Employment

No Stable
Employment

Experimental Group

10

17

Treatment As Usual (TAU)

7

77

  1. Compute the chi-square. List the numerator.
  2. List the denominator.
  3. Using the numbers in the contingency table, calculate the percentage of veterans in the Experimental Group who achieved stable employment.
  4. Using the numbers in the contingency table, calculate the percentage of veterans in the TAU Group who achieved stable employment.
  5. Write your interpretation of the results, as you would in an APA-formatted journal.
