We choose two samples:

One with inhabitants of City A
One with inhabitants of City B
The height and weight of samples were measured. The differences of height and weight of samples of two cities were statistically significant (P-value < .05).

How can I calculate which of these differences (height or weight) is more prominant between the inhabitants of the two cities?

Can someone give me an example using SPSS?
Thank you
