Feb 17th, 2015

The higher the z score, the better it is ( if positive direction or increase is desired)

Suppose we want to compare the performance of students in History Class and students in Mathematics class, then z score will be a better tool.

or sales of two territories are to be compared;

Territory 1 : average 1000 SD 100

Territory 2 : average 800 SD 50

Suppose territory 2 has low potential, z score will be better tool
