To prepare for this Assignment, review the Week 4 Handout: Chi-Square Findings and follow the instructions.

Submit a 1-page paper of the following:

 An analysis of the relationship between study design and statistical analysis used in the case study that includes:
 

• An explanation of why you think that the agency created a plan to evaluate the program
• An explanation of why the social work agency in the case study chose to use a chi square statistic to evaluate whether there is a difference between those who participated in the program and those who did not (Hint: Think about the level of measurement of the variables)
• A description of the research design in terms of observations (O) and interventions (X) for each group.
  • Interpret the chi-square output data. What do the data say about the program?
