If the data set has a mean of 50 and a variance of 16, what is the standard deviation?

If the data set has a mean of 50 and a variance of 16, what is the standard deviation?

Step 1: Understand that variance is a measure of how spread out the numbers in a data set are.
Step 2: Know that the standard deviation is a value that tells us how much the numbers in the data set typically differ from the mean.
Step 3: Remember the formula to find the standard deviation: Standard Deviation = √Variance.
Step 4: In this case, the variance is given as 16.
Step 5: Calculate the square root of the variance: √16.
Step 6: Find the square root of 16, which is 4.
Step 7: Conclude that the standard deviation is 4.
