👉 Wariance is a measure of how much a value fluctuates from its mean. It is calculated by taking the difference between each value and the mean, then squaring the result, and finally dividing by the number of values considered. This process is repeated for all possible values to arrive at an average value that represents the overall variability or dispersion of the data. Wariance can be used in various fields such as finance, economics, engineering, and statistical analysis to measure how much a variable changes over time
