While Standard Deviation is primarily used for numeric data, it can be applied to categorical data by converting it into a numerical representation, such as using binary values (0s and 1s) to represent categories.

• Standard Deviation is always a large number: Incorrect, Standard Deviation can be small or large depending on the data distribution.
• Overreliance: Relying solely on Standard Deviation can overlook other important factors in decision-making.

Imagine a group of students' heights: one student might be 5 feet 2 inches, another 5 feet 8 inches, and a third 6 feet 1 inch. If the average height is 5 feet 7 inches, the Standard Deviation would reveal how much each student's height deviates from the average.
