Frequently Asked Questions (FAQ)
What is the standard deviation? It measures the spread or variability of a set of data values around the mean.
How is the standard deviation calculated? Standard deviation is calculated by finding the square root of the variance.
What is variance? Variance is the average of the squared differences from the mean.
Why is standard deviation important? It helps in understanding the consistency of a data set and its risk, especially in fields like finance.
