Questions & Step-by-Step Solutions

What is the coefficient of variation if the mean is 50 and the standard deviation is 10?
  • Step 1: Identify the mean value, which is given as 50.
  • Step 2: Identify the standard deviation value, which is given as 10.
  • Step 3: Use the formula for the coefficient of variation: (Standard deviation / Mean) * 100.
  • Step 4: Substitute the values into the formula: (10 / 50) * 100.
  • Step 5: Calculate the division: 10 divided by 50 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%.
