"Webb13 mars 2024 · Subtract 2,700 from 2,500, divide the result by 2,700, then multiply by 100: percent deviation = (2,500 - 2,700) / 2,700 x 100 = -200 / 2,700 x 100 = -7.41 percent. The negative sign in your answer signifies that your mean is lower than the expected mean. If the percent deviation is positive, it signifies your mean is higher than expected.
