Q
Q: If the standard deviation of a data set is 5, what is the variance?
Solution:
Variance is the square of the standard deviation. Variance = 5² = 25.
Steps: 5
Show Steps
Step 1: Understand that standard deviation is a measure of how spread out the numbers in a data set are.
Step 2: Know that variance is another measure of spread, and it is calculated by squaring the standard deviation.
Step 3: Since the standard deviation given is 5, you need to square this number.
Step 4: Calculate 5 squared, which is 5 * 5.
Step 5: The result of 5 * 5 is 25, so the variance is 25.
