absolute deviation = | true value - experimental value|
(1) absolute deviation = |22.52 - 22.64| = 0.12
(2) absolute deviation = |22.52 - 22.58| = 0.06
(3) absolute deviation = |22.52 - 22.62| = 0.1
Two students determine the percentage of lead in a sample as a laboratory exercise. The true percentage is 22.52%. The students results for three determinations are as follows:
1. 22.52, 22.48, 22.54
2. 22.64, 22.58, 22.62
Calculate the average value of the absolute deviations of each measurement from the average for the second set.
