Generally, the standard deviation (represented by sigma, an O with a line at the top) would be used to measure variability. The standard deviation represents the average distance of data from the mean.
Another measure is variance, which is the standard deviation squared.
Lastly, you might use the interquartile range, which is often the range of the middle 50% of the data.
Standard deviation would be used in statistics.

A measure used to describe the variability of data distribution is the standard deviation. It quantifies the amount of dispersion or spread in a set of values, indicating how much individual data points differ from the mean. A higher standard deviation signifies greater variability, while a lower standard deviation indicates that the data points are closer to the mean. Other measures of variability include variance and range.
Why are measures of variability essential to inferential statistics?
The usual measures of variability cannot.
The term used to describe the spread of values of a variable is "dispersion." Dispersion indicates how much the values in a dataset differ from the average or mean value. Common measures of dispersion include range, variance, and standard deviation, which provide insights into the variability and distribution of the data.

Statistics is a study in uncertainty. Statistical techniques are used to assign probabilities to events and, since these are probabilities, certainty is rare. As a consequence, the methods yield answers with a degree of variability.
The range, inter-quartile range (IQR), mean absolute deviation [from the mean], variance and standard deviation are some of the many measures of variability.
It measures the error or variability in predicting Y.
Sets of data have many characteristics. The central location (mean, median) is one measure. But you can have different data sets with the same mean. So a measure of dispersion is used to determine whether there is a little or a lot of variability within the set. Sometimes it is necessary to look at higher order measures like the skewness, kurtosis.
