Frequently Asked Questions
Frequently Asked Questions
What does variance measure?
Variance measures how far numbers in a dataset are from the mean. A higher variance means more spread out data.
What's the difference between variance and standard deviation?
Standard deviation is the square root of variance. It's in the same units as the original data, making it easier to interpret.
