Find the interquartile range of the data. 68, 82, 44, 79, 94, 60, 78, 70, 59

Answer:21

Step-by-step explanation:

To find the IQR, start by arranging the numbers in your data set from lowest to highest. Then, divide your data set in half and find the median of both the lower and upper half. If you have an odd amount of numbers, don't include the middle number.

44,59,60,68,70,78,79,82,94

44,59,60,68, 78,79,82,94

lower half (above) upper half (above)

median for upper half:80.5

median for lower half:59.5

80.5-59.5=21

Interquartile Range: 21
