A set of numbers has a variance of 36. What is the standard deviation? (2019)
Step 1: Understand that variance is a measure of how spread out the numbers in a set are.
Step 2: Know that standard deviation is a related measure that tells us how much the numbers typically differ from the average.
Step 3: Remember the formula: Standard Deviation (SD) is the square root of the variance.
Step 4: Since the variance given is 36, we need to find the square root of 36.
Step 5: Calculate the square root of 36, which is 6.
Step 6: Conclude that the standard deviation is 6.
