Francine makes several measurements of the mass of a metal block. The data set is shown in the table below. Measurement Mass of
metal block (g) 1 20.73 2 20.76 3 20.68 4 20.75 After analyzing this data set, Francine calculates a value of 20.73 g. Which of these characteristics has been calculated?
The characteristic being calculated here is the mean or the average of the data set. To check: (20.73 + 20.76 + 20.68 + 20.75)/4 [we divide it by 4 because there are 4 numbers] = 82.92 / 4 = 20.73
