# Project #57824 - statistics/Ethical issues in Research()

My Budget for this is \$125-135

Hi I posted this project before, but it was not correct; I need someone with experience in statistics and that can hand right the problems and show all work. I have received feedback from my instructor and what is needed; I will also provide the formulas that must be used.Â

Â

Â

Ethical issues in Research()

Â

Read about both the Humphrey and Milgram study. I have included some links, however you can learn about these studies however you wish.

Then redesign either the Humphrey or Milgram study to accomplish the same research purpose but to avoid the ethical issues.

Â

4. Class material and concepts.

Â

For each term

Â

a. Define the term

Â

b. Apply to the following research scenario.

Â

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 seniorsÃ¢â‚¬â„¢ depression level based on their participation in a Person Centered care program. (22 points)

Â

Â

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?

Â

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

Â

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

Â

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

Â

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)

Â

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

Â

1. Group Selection:

Â

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 homeÃ¢â‚¬â€equally splitting the entire group among the 4 groups.)

Group1____________________________________________________________________

Group 2____________________________________________________________________

Group 3____________________________________________________________________

Group 4____________________________________________________________________

Â

g. Z test has nothing to do with a mean.....see lectures...

Â

h. explain.001 See lectures, your definition does not make sense

Â

i.need example of snowball sampling for this problem

Â

j. this application is not about a mental exam...

Â

Â k Why snowball for 20 seniors(not necessarily men)

Â

5. I do not understand at all what you did here. Please go back and read the instructions and answer each question

Â

a. I asked for the REsearch question.For Design a Solomon 4 group experiment to show the effect of participating in a Silver Sneakers Program for 6 months on mobility---i did not ask for HYPoTHESIS

Â

Â

Â

These are the formuals that must be used

Â

It is important to know how to calculate the Standard Deviation, as it is used in other calculations.

Â

 Formula: The formula for standard deviation is: Â  where: S= Standard Deviation Â = Sum of X = individual score M = mean orÂ

Â

Â

Â

ind the Critical score, you need to determine the Degrees of Freedom. Degrees of freedom adjusts for sample size differences. For the T-test, degrees of freedom is:

Â

 dF= n1 + n2 - 2

Â

n is the sample size. The numbers next to each n indicates either sample 1 and sample 2.

Â

 Formula: The formula for T-test is: Â

Z-test

Â

Last week we learned about the T-test, which compared the means of two groups. Now we will learn about the Z-test, which compares proportions or percents of each group. Here is the z-test formula:

Â

Â

Â

• P1Â = Proportion of group one
• P2Â = Proportion of group 2
• p = proportion of group 1 + proportion of group 2
• q = 1 - p
