3.Figure the correlation coefficient.

Why was my question cancelled?Should I try a new tutoring system? Provide a response to the following prompts. This question is based on a worksheet of different team members that have different answers.

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:

PersonDexterityAnxiety

1110

218

324

44 -2

Describe the process your research team would go through by completing the following:

a scatter diagram of the scores.

2.Describe in words the general pattern of correlation, if any.

The pattern of the correlation shows that anxiety and dexterity does have a negative relationship. As the anxiety scores go higher, you will see lower dexterity scores. This is also vice versa.

3.Figure the correlation coefficient.

The coefficient (r) is = - 0.9603

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).

When speaking of the correlation, it can be either a positive or negative number. The correlation coefficient measures the direction and strength of a linear relationship. For example, a person who has a higher anxiety level will have a lower dexterity. It also works vice versa. For example, if your anxiety level is lower, the dexterity of a person is higher

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.

Dexterity and anxiety have no relationship at all.

It is possible to say that the levels an individual anxiety and dexterity tests could possibly have no relation at all. If an individual is showing no signs of anxiety with a lower dexterity score, then you cannot rule that the two have anything in common.

A negative relationship between dexterity and anxiety.

When a person is anxious, then their anxiety levels are much higher, causing their dexterity levels to be lower. This could indicate that there is a possibility that a person could not be comfortable or confident with things that cause them to be anxious.

A positive relationship dexterity and anxiety.

Lower anxiety levels reveal higher dexterity levels, which could definitely come from a person who is confident or comfortable with a situation.
