Wyoming has a dropout rate of about 7%.. Into what quartile does this rate fall:
Q3. Outliers
Lower limit Q1 - 1.5 x (1QR)
Upper limit Q3 + 1.5 x (1QR)
Students from a statistics class werte asked to record their heights in inches, the heights are as follows
65 72 68 64 60 55 73 71 52 63 61 74
69 67 74 50 4 75 67 62 66 80 64 65
Make a box and whisker plot of the data
Find the value of the interquartile range (1QR)
Multiply the 1QR by 1.5 and find the lower and upper limits.
Are thee any data values below the lower limit: above the upper limit?
List any suspected outliers. What might be some explanations for the outliers:
