Common questions

Should I use sample or population standard deviation?

Use the sample version when your data is a subset of a larger group; use the population version when you have every value.

What if there are multiple modes?

The data is multimodal. Report all modes or use the median instead.

Does it handle outliers?

It includes them. The median and interquartile range are more robust when outliers are present.
