how to find relative average deviation percent
To find this type of percent deviation, subtract the known value from the mean, divide the result by the known value and multiply by 100. Suppose you did an experiment to determine the density of aluminum, and came up with a mean density of 2,500 kilograms per meter squared.o find this type of percent deviation, subtract the known value from the mean, divide the result by the known value and multiply by 100.
