Answer
Standardizing random variables allows comparing variables with different means and standard deviations on the same scale.
Solution
The primary reason for standardizing random variables is to measure variables with different means and standard deviations on a single scale.
Standardization transforms random variables to have a mean of 0 and a standard deviation of 1, allowing for comparison across different distributions. This process enables the analysis of variables that may have different units or scales, making it easier to interpret and compare their values.

Standardizing random variables is like putting on a pair of magical lenses that allow you to see all data on the same playing field! By transforming variables to a common scale—often using z-scores—you can compare and interpret diverse datasets more easily, regardless of their original units, means, or standard deviations. In practice, this is super useful! For example, if you're comparing test scores across different subjects with varying difficulty (and grading standards), standardization helps you understand which students truly excelled relative to their peers. It's a crucial step in any data analysis toolkit!
