What is the mean median mode and range of 65 56 57 75 76 66 64?

65,56,57,75,76 ,68,64. First of all rearrange the terms in RANK order.

Hence

56,57,64,65,66,75,76.

MEDIAN. Select the absolute middle term from the rank order, which is 65. 65 is the Median.

NB There are three terms to either side of this number.

MODE. Select the term that occurs most frequently. Since all the terms occur only once, then you select the middle term, which is 65 again.

MEAN. You add all the terms and then divide by the number of terms. Hence

[56+57+64+65+66+75+76] / 7 =>

459/7 =>

65.57142857... ~ 65.57 ( 2 d.p.) ( The Mean)

RANGE .

is the difference between the highest value and the lowest value.

Hence 76 - 56 = 20 ( The range)
