Definition
A statistical measure is a numerical value that summarizes or describes a specific characteristic of a set of data. It provides insights into the distribution, variability, or relationship within the data.
The standard deviation measures how much individual data points deviate from the mean value. It gives us an idea about the spread of data around the mean.
Variance is another measure of dispersion that quantifies how much each individual data point differs from the mean, squared. It provides insights into the overall variability in a dataset.
