In a data set, the mean is 20 and the standard deviation is 4. What is the coefficient of variation?

Correct Answer: 20%

Step 1: Identify the mean of the data set, which is given as 20.
Step 2: Identify the standard deviation of the data set, which is given as 4.
Step 3: Use the formula for the coefficient of variation: Coefficient of Variation = (Standard Deviation / Mean) * 100.
Step 4: Substitute the values into the formula: Coefficient of Variation = (4 / 20) * 100.
Step 5: Calculate the division: 4 divided by 20 equals 0.2.
Step 6: Multiply the result by 100: 0.2 * 100 equals 20.
Step 7: Conclude that the coefficient of variation is 20%.
