If the standard deviation of a given data is 53, what is the variance?
Answer Details
The variance is a measure of how spread out a set of data is from its mean. It is calculated by squaring the standard deviation. In this case, the standard deviation is given as 53. So, to find the variance, we simply need to square 53. 53^2 = 2809 Therefore, the variance of the given data is 2809. To summarize, the variance is calculated by squaring the standard deviation, and in this case, the variance is 2809 since the standard deviation is 53.
