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
  1. Sketch a graph showing the relationship between x and y. Compute the Pearson correlation between x and y.
  2. Sketch a graph showing the relationship between y and z. Compute the Pearson correlation between y and z.
  3. Given the results of parts a and b, what would you predict for the correlation between x and z?
  4. Sketch a graph showing the relationship between x and z. Compute the Pearson correlation for these data.
  5. 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.
