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 that your research team would go through by completing the following:

- Make a scatter diagram of the scores.

- Describe in words the general pattern of correlation, if any.
- Figure the correlation coefficient.
- Figure whether the correlation is statistically significant (use the .05 significance level, two-tailed).

- 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). - Give three logically possible directions of causality, indicating for each direction whether it is a reasonable explanation for the correlation in light of the variables involved (and why).
