Module 3 Assignment 1: Hypothesis Testing
Generate a z-score and p value (proportion in the tail beyond z) for the mean concentration data points in the table below using four pairs of parameters in problems 1-4. For each p value, make a decision to retain or reject the null hypothesis and write an APA formatted statement of your conclusion. 1 point for each correct z-score, p value and APA statement (must be entirely correct). An example of an APA formatted statement of your conclusion is as follows: Child 1’s mean concentration in seconds, M = 75, was significantly different, z = -2.50, p = .00, than mu = 10. 120 points possible.
When you have done all 40 problems, answer the following question: What happens to the "significance" of each child’s data as sigma increases and the data become progressively more dispersed? 5 points

Grading Criteria
Given a research scenario, data points, set of population parameters and alpha set at p = .05, is the student able to generate the correct:
1) pair of hypotheses for each data point?
2) a z statistic and p value for each data point?
3) decision about the null hypothesis for each data point?
4) APA-formatted statement of results for each data point?
Total points: 125
This assignment informs instructors how well the student understands the essentials of hypothesis testing using z-scores.
ASSIGNMENT 2

A Survey of 50 Clients
In January 08, fifty clients of a county Mental Health Mental Retardation (MHMR) center were surveyed regarding their satisfaction with services. The clients filled out the survey on completion of treatment. In June 08, the clients were telephoned and re-surveyed and were asked to rate their overall satisfaction again.

Variables in the working file
For each research question below , describe in your WORD document the application of the seven steps of the hypothesis testing model.
Step 1: State the hypothesis (null and alternate)
Step 2: State your alpha (unless requested otherwise, this is always set to alpha = .05)
Step 3: Collect the data (use one of the data sets).
Step 4: Calculate your statistic and p value (this is where you run SPSS and examine your output files).
Step 5: Retain or reject the null hypothesis. (This is where you report the results of your analyses
t (df) = t value, p = sig. level).
Step 6: Assess the Risk of Type I and Type II Error (did the data meet the assumptions of the statistic; effect size; and sample size).
Step 7: State your results in APA style and format.
MODULE 4 Application Assignments
Question 1: How does the MHMR compare to the state’s figures on providing services to first-time admissions?
The State published a report that, on average, MHMR centers provide about 60% of counseling services to first time patients. Is this MHMR’s percent of services provided different than the state average?
1. Use Select Cases to choose First time patients (Newpatient = 0).
2. Run a single sample t-test using Usage as the dependent variable, and 60.0 as the test value.
3. Report the descriptive statistics, assumptions tests, as well as test of statistical significance.
Question 2: Is there a difference between first time and repeat admissions in their overall satisfaction with MHMR services as rated in January?
1. Run an Independent Samples t-test
2. Use Newpatient as the independent variable.
3. Use Overall Satisfaction in January (Osatjan) as the dependent variable.
4. Report the descriptive statistics, assumptions tests, as well as tests of statistical significance.
Question 3: Has satisfaction with MHMR services changed since the January survey?
1. Run the Paired Samples t-test
2. Use Overall Satisfaction in January and Overall Satisfaction in June as the variable pair.
3. Report the descriptive statistics, assumptions tests, as well as tests of statistical significance.
Write a brief conclusion statement summarizing your results. What can you tell this MHMR about client satisfaction? What could you suggest they do to improve?
