How Standard Deviation Works

Standard deviation is a fundamental statistical concept that can be understood by anyone with basic math skills.

Standard deviation is typically used with numerical data. For non-numerical data, other statistical measures, like the mode or median, may be more suitable.

Can I use standard deviation with non-numerical data?

How is standard deviation used in real-life scenarios?

Imagine you're at a school where students' heights are recorded. You want to know how spread out the heights are. Standard deviation is a statistical measure that helps you understand this spread. It calculates the average distance of each data point from the mean (average) value. The higher the standard deviation, the more spread out the data is. For example, if a student's height is 5 feet, and the average height is 5.5 feet, a high standard deviation indicates that heights vary widely among students.

• Data analysts and scientists

Standard deviation is often calculated and re-calculated as new data becomes available, allowing for ongoing evaluation and adjustment.
