Produce the Pearson correlation matrix for all variables except the name of the printer. What are the two strongest relationships shown in the Pearson correlation matrix?
The correlation matrix is given in a table below ("Annotated SPSS Output: Correlation", 2016):
The strongest correlation coefficient is between Text Cost and Color Photo Cost (r=0.606, p=0.017). The next strongest correlation is between Price and Color Photo Time (r=-0.518, p=0.048). There is a strong positive linear relationship between Text Cost and Color Photo Cost. There is a strong negative relation between Price and Color Photo Time. These relationships are one we would expect, because lesser time spent on producing color photo usually costs higher. (b) If ...
