Question 1 Report
If the standard deviation of a given data is 8.2, find its variance
Answer Details
To find the variance of a given data, we need to square the standard deviation. This is because variance is defined as the average of the squared differences from the mean.
In this case, the standard deviation is given as 8.2. To find the variance, we simply square this value:
Variance = (Standard deviation)^2
= 8.2^2
= 67.24
Therefore, the variance of the given data is 67.24.
In summary, to find the variance of a given data, we square the standard deviation. In this case, since the standard deviation is given as 8.2, the variance is found by squaring 8.2, which gives a value of 67.24.
