Question

analyze meaningful versus meaningless variables reported in descriptive statistics

Answer 1

The variables reported in Descriptive Statistics can be categorized into meaningful variables and meaningless variables as follows:

In order to consider a variable as meaningful, we should ask ourselves, " Can this be affected mathematically?". If it can be mathematically affected, it is categorized as meaningful variable.

For example, consider the data consisting of heights of all students in a class. Since height being a numerical value can be affected mathematically. So, height is a meaningful variable.

We cannot average gender, as it is a qualitative variable. So, gender is a meaningless variable.
