Questions & Step-by-Step Solutions

If the standard deviation of a data set is 4, what is the variance?
Correct Answer: 16
  • Step 1: Understand that the 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: Take the given standard deviation, which is 4.
  • Step 4: Square the standard deviation: 4 squared (4 * 4) equals 16.
  • Step 5: Conclude that the variance of the data set is 16.
  • Standard Deviation and Variance – Standard deviation is the square root of variance, and variance is the square of the standard deviation.
