Suppose the scores of seven members of a women’s golf team are 68, 62, 60, 64, 70, 66, and 72. Find the mean, median, and midran ge.
1 answer:
Mean - add up all of the scores, and divide it by the number of members: 68 + 62 + 60 + 64 + 70 + 66 + 72 = 462 462 / 7 = 66 ANSWER: The mean is 66 Median - write out all the numbers in order, and select the middle value: 60, 62, 64, 66 , 68, 70, 72ANSWER: As you can see, 66 is the middle value.Midrange - find the mean (average) of the smallest and largest number: Largest number: 72 Smallest number: 60 Midrange: 72 + 60 = 132 132 / 2 = 66 ANSWER: So the midrange is 66
