The Population Standard Deviation Formula: A Comprehensive Guide

One common misconception about the population standard deviation formula is that it is a measure of central tendency. In reality, it is a measure of variability. Another misconception is that it can be calculated for categorical data. However, the population standard deviation formula is only applicable to numerical data.
