11.  What did you change and why?

12. Is your study equally Valid to the Original Study?  Explain.

1. Design a survey to give at a local Senior Center to demonstrate the need for a Silver Sneakers program in your county. (13 points) Info on Silver Sneakers: https://www.youtube.com/watch?v=80dcEsxXUmA

Include:

a. Informed Consent (separate page—be sure to include the basic elements discussed in class lecture and sample)

b. Title

c. Instructions (always labeled)

d. Relevant Demographics

e. Relevant questions to assess the need for Silver Sneakers in your community

f. a contingency question

g. one matrix question with four sections.(Remember a theme)

Minimum number of questions: 10.

3. Levels of Measurement. Name and define the different levels of measurement.  Then for each level of measurement give one example from the spreadsheet data provided.(4 POINTS)

4. Class material and concepts.

For each term

a. Define the term

b. Apply to the following research scenario.

SCENARIO: You are conducting research at a local Nursing home with 20 seniors over a period of 6 months.  You are assessing the change in the seniors’ depression level based on their participation in a Person Centered care program.  (22 points)

1. What is a Mean and what data would you use it for in this study?

2. What is Validity?  And how would you ensure this study was Valid?

3. What is the Dependent variable?

4. What is the Independent variable?

5. What is a Standard Deviation and how might you use it in this study.

6. What does a T test do?  And what would you use it for in this study?

7. What does a Z test do?  And how might you use it in this study?

8. What is a .001 level of Significance?

1. What is a snowball sampling method?  How would you use it in this study?

1. What is Reliability?  And how would you ensure it in this study?

1. What type of Sampling method would you suggest for 20 seniors.  And Why?

5. Design a Solomon 4 group experiment to show the effect of participating in a Silver Sneakers Program for 6 months on mobility. (15 points)

a. Identify your research question (Hint: take it from the assignment above)

1. Group Selection:

Use the Participants from the data sheet. You must use all participants(12!)

For all groups, match for type of living arrangement and use a ratio selection for gender. Identify specific participants by name, gender and type of living arrangement. You must use and label all participants. (For Example: Ellen,(f),apartment.)

Some hints: To use a ratio selection for gender find the ratio of men-women for the entire group(12) and then have the same ratio in each group (so if  you had 100 men and 20 women in a study-the ratio would be 100/20, which is reduced to 10/2 which is reduced to 5/1-so for each group you would have 5 men to 1 woman)

To match for type of living arrangement. All groups need to look the same. (For example if you had 40 participants living at home, each group would have 10 participants living at home—equally splitting the entire group among the 4 groups.)

Group1____________________________________________________________________

Group 2____________________________________________________________________

Group 3____________________________________________________________________

Group 4____________________________________________________________________

c. Describe your intervention or treatment:

1. Identify your IV:______________________ and DV:___________________________

e. Outline and describe your process for conducting this Solomon 4 group experiment. Be sure to draw a chart. Explain the process from participant selection through data analysis.

f .How would you analyze your data? What statistics would you use and why?

ALL questions from here to end of exam must be written out by hand. Always show full formula before solving and then solve step by step. Please SHOW ALL OF YOUR WORK!!

6. Measures of Central Tendency.

a. Please name, define and find the measures of central tendency for number of Silver Sneaker sessions for women. (6 POINTS) SHOW ALL WORK. Include Solving the equation step by step if there is an equation.

b. Which is the best measure of Central tendency for this data and why?
7. Find the standard deviation for number of Silver Sneaker sessions for women.   (10 points)

SHOW ALL WORK.

What percent of a normal distribution falls between the mean and - 1 standard deviations? _____

What percent of this data falls between the mean and -1 sd? _______ (5 points)

9. Compare males and females for average number of Silver Sneaker sessions. (10 points)

What test of significance did you use: _____

Level of significance_____

Critical score_____

Calculated score________

What did you find out?  Explain your findings.
