Why would standard z having no units of measurements be desirable for comparing data sets with different units of measurements?

Step 1

Standard deviations from the mean serve as a unit of measurement for the Z-score. It is a statistical evaluation of how closely a score varies from the group mean. The data point score and mean score are the same if the Z-score is).

Step 2

$Z=\frac{x-\mu}{\sigma}$

Step 3

It is used to compare different data sets with different means and sd (standard deviations). It's a universal compare for normal distribution in statistics.z score shows how far away a single data point is from the mean relatively. Lower z score means closer to the meanwhile higher means more far away. Hence .z-scores are desirable for comparing data sets with different units of measurement.
