13. Mean and median are different measures of central tendency for a numerical dataset. Figure 1: Example data values stored in a one-dimensional array, DATA, which contains 10 elements [0] [1] [2] [3] [4] [5] [6] [7] [8] [9] 2 3 3 6 5 9 10 100 14 17 The mean of the data values stored in a one-dimensional array can be determined as follows: y Add up all the numbers in the one-dimensional array. y Divide this sum by how many numbers there are. The mean of the data values stored in the DATA array in Figure 1 is 16.9.
