Compare the data sets by making two box-and-whisker plots above one number line. grades of class a: 71, 78, 95, 68, 91, 95, 85, 76, 94, 77, 79, 95, 82, 93, 92, 70 grades of class b: 86, 98, 99, 64, 80, 89, 63, 95, 70, 69, 81, 77, 72, 87, 96, 79

Unfortunately, i cannot physically draw a box-and-whisker plot on the computer, but i can explain how.  first, draw a number line and label it so it includes all of your data values.  second, determine the lower extreme. draw a dot above the number on your number line.third, determine the median. draw a dot above the number on your number line.  fourth, calculate the second quartile. after drawing a dot above the number on your number line, draw a short line that goes through your dot and then connect the lower extreme's dot to the second quartile dot. draw a line of the same length through the median and connect the two lines at the top and bottom.fifth, identify the upper extreme and draw a dot above the number on the number line.sixth,  calculate the third quartile. then follow the same steps as with the second quartile.

A= b/2 because u simplying both sides of equation
