Four research participants take a test of manual dexterity (high scores mean better dexterity) and an anxiety test (high scores mean more anxiety)
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 your research
team would go through by completing the following: 1. Create a scatter
diagram of the scores, which should be a negative direction. 2. Describe
in words the general pattern of correlation, if any. 3. Figure the
correlation coefficient. 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). 5. Provide 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. Explain why.
