BASED OFF OF THE DATASET IN “ADDITIONAL FILES”

 

Question 1: In Fall 07, the MHMR ran public service announcements advertising treatment resources for mental health, substance abuse and dual diagnoses (both). Does the distribution of pre-existing conditions (Mental health, Substance Abuse or Both) differ from what one would expect by chance?

 

1. Run a Chi Square Goodness-of-Fit using PreExisting Condition as the variable with “all categories equal”.

 

2. Report the observed and expected values and the tests of statistical significance.

 

Question 2. The MHMR received data from the State indicated that MHMR facilities tend to attract more substance abuse cases than mental health or dual diagnosis clients.

 

1. Does the distribution of clients (Mental health, Substance Abuse or Both) differ from the State data?
2. Run a Chi Square Goodness-of-Fit using Type of Treatment as the variable with “all categories unequal” with 12, 26, and 12 as the expected values.
3. Report the observed and expected values and the tests of statistical significance.

 

Question 3: The MHMR would like to know if there is a relationship between the Type of Patient and Court Ordered.

 

1. Run Chi Square Independence test (Crosstabs) using Newpatient in the rows and Court in the column.

 

2. Use the Chi Square and the Phi Coefficient to

evaluate the relationship and statistical significance.

 

3. Report the observed and expected values and the tests of statistical significance.

 

Write a brief conclusion statement summarizing your results. What can you tell this MHMR about the kinds of clients that use this facility? Is utilization in this MHMR similar or different than the state? What type of patient is the most frequent user of these services?
