Question: In the following data, there are three scores X, Y and Z for each of the n=5 individuals:
| X | Y | Z |
| 3 | 5 | 5 |
| 4 | 3 | 2 |
| 2 | 4 | 6 |
| 1 | 1 | 3 |
| 0 | 2 | 4 |
A) Sketch a graph showing the relationship between x and y. Compute the Pearson correlation between x and y.
B) Sketch a graph showing the relationship between y and z. Compute the Pearson correlation between y and z.
C) Given the results of parts a and b, what would you predict for the correlation between x and z?
D) Sketch a graph showing the relationship between x and z. Compute the Pearson correlation for these data.
E) What general conclusion can you make concerning relationships among correlations? If x is related to y and y is related to z, does this necessarily mean that x is related to z.
