Variance - Wikipedia
Variance has a central role in statistics, where some ideas that use it include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and Monte Carlo sampling.

Variance - GeeksforGeeks
Variance is defined as the square of the standard deviation, i.e., taking the square of the standard deviation for any group of data gives us the variance of that data set.

What Is Variance in Statistics? Definition, Formula, and Example
Variance measures how far data points are spread out from the mean. A higher variance indicates greater variability and risk, while a lower variance indicates more consistent results.

VARIANCE Definition & Meaning - Merriam-Webster
variance implies a clash between persons or things owing to a difference in nature, opinion, or interest.

3 Ways to Calculate Variance - wikiHow
What is variance? Variance is a measure of how spread out a data set is, and we calculate it by finding the average of each data point's squared difference from the mean. It's useful when creating statistical models since low variance can be a sign that you are over-fitting your data.

Standard Deviation and Variance - Math is Fun
Deviation means how far from the normal. The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma) The formula is easy: it is the square root of the Variance. So now you ask, "What's the Variance?" The Variance is defined as: The average of the squared differences from the Mean.

Variance: Definition, Step by Step Examples - Statistics How To
Variance measures the spread between numbers in a data set. It helps us determine how far each number in the set is from the mean or average, and from every other number in the set.

Variance Calculator
Variance is a measure of dispersion of data points from the mean. Low variance indicates that data points are generally similar and do not vary widely from the mean. High variance indicates that data values have greater variability and are more widely dispersed from the mean.

Variance — Definition, Formula & Examples
Variance is a number that tells you how spread out the values in a data set are from the mean. A high variance means the data is widely spread; a low variance means the values are close together.
