Is sigma square equal to variance?

Yes, sigma squared (σ²) represents the variance of a population in statistics. Variance measures the dispersion of a set of values around their mean, and it is calculated as the average of the squared differences from the mean. In summary, σ² is simply the symbol used to denote variance in statistical formulas.


What is the purpose of calculating variance in statistics?

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.


Why we calculate the variance and standard deviation?

They are measures of the spread of the data and constitute one of the key descriptive statistics.


What are the advantages and disadvantages of inferential statistics?
