Assessment Brief
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).
