The purpose of calculating variance in statistics is to measure the degree of variation or dispersion in a set of data points. It quantifies how much individual data points differ from the mean, providing insights into the spread of the data. A higher variance indicates greater variability, while a lower variance suggests that the data points are closer to the mean. This information is crucial for assessing risk, making predictions, and understanding the reliability of statistical conclusions.

How is variance used to measure risk?
In finance, risk of investments may be measured by calculating the variance and standard deviation of the distribution of returns on those investments. Variance measures how far in either direction the amount of the returns may deviate from the mean.

What is the purpose of calculating the mean and the variance?
Calculating the mean helps to understand the central tendency of a data set, while calculating the variance provides information about the spread or dispersion of the data points around the mean. Together, the mean and variance provide a summary of the data distribution, enabling comparisons and making statistical inferences.
