Q
Q: If the variance of a data set is 16, what is the standard deviation?
Solution:
Standard deviation = √variance = √16 = 4.
Steps: 5
Show Steps
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 simply the square root of the variance.
Step 3: Since the variance given is 16, we need to find the square root of 16.
Step 4: Calculate the square root of 16, which is 4.
Step 5: Conclude that the standard deviation is 4.
