University of Phoenix Material                          Correlation Study 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:   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).                 References   Copyright ©2013 by Pearson Education, Inc.  All rights reserved.  Used with permission.
