Providea response to the following prompts. Utilize electronic readings for the week and our textbook to help you answer appropriately.Cite/Referenceall sources using proper APA 7thedition format.Citing and referencing our course textbook isREQUIREDon ALL practice worksheets.
Note:Each team member should compute the following questions and submit them to the Learning Team forum. The team should thendiscuss each team member’s answersto 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:
PersonDexterityAnxiety
1110
218
324
44-2
Describe the process your research team would go through by completing the following:
1.Create a scatter diagram of the scores (include the line of best fit please).
2.Describe in words the general pattern of correlation, if any. Discussstrength AND direction.
The fitted line starts from the top left and ends at the bottom right. There is negative relation between variables. Therefore, direction is negative. All the point near the fitted line. Therefore, strength of relation is strong.
3.Figure the correlation coefficient.
The correlation is -0.9799579 using the excel formula “=CORREL (B2:C5,B2:C)
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,Zscores, 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.
