Question

# correlation study worksheet psy 315<br/>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).
