Verified step by step guidance1
Identify the variance value from problem #2, which is a measure of how much the data points differ from the mean.
Recall the relationship between variance and standard deviation: the standard deviation is the square root of the variance.
Apply the formula for standard deviation: \( \text{Standard Deviation} = \sqrt{\text{Variance}} \).
Substitute the variance value into the formula to find the standard deviation.
Calculate the square root of the variance to determine the standard deviation, ensuring to check your calculations for accuracy.
