Midrange
Midrange: The number halfway between the lowest data value (L) and the highest data value (H).
The third measure of central tendency is midrange. Midrange is the number halfway between the lowest data value (L) and the highest data value (H). To find the midrange, use the following formula to average the low and high values: Midrange = `(H+L)/2`.
For example, to identify the midrange for the dataset {1, 2, 5, 6, 7, 5, 4, 5}, determine the highest and lowest data value (H = 7 and L = 1). Then, use those values to complete the formula: Midrange `= (H+L)/2 = (7+1)/2 = 8/2 = 4`.
The midrange is 4.
