Assignment: Practice Worksheet
Provide a response to the following prompts. Utilize electronic readings for the week and our textbook to help you answer appropriately.
Note: Each team member should compute the following questions and submit them to the Learning Team forum. The team should then discuss each team member's answers to ascertain the correct answer for each question. Once your team has answered all the questions, submit a finalized team worksheet.
Your research team has been tasked with finding the correlation of the following scenario:
Four research participants take a test of manual dexterity (high scores mean better dexterity) and an anxiety test (high scores mean more anxiety). The scores are as follows:
Person Dexterity Anxiety
1 1 10
2 1 8
3 2 4
4 4 -2
Describe the process your research team would go through by completing the following:
1. Create a scatter diagram of the scores.
2. Describe in words the general pattern of correlation, if any. Discuss strength AND direction.
3. Figure the correlation coefficient.
4. Explain the logic of what you have done, writing as if you are speaking to someone who has never heard of correlation (but who does understand the mean, standard deviation, Z scores, and hypothesis testing).
5. Provide three logically possible directions of causality, indicating for each direction whether it is a reasonable explanation for the correlation based on the variables involved. Explain your answer.
Format your assignment according to the following formatting requirements:
1. The answer should be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.
2. The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.
3. Also include a reference page. The Citations and references should follow APA format. The reference page is not included in the required page length.
