Box and Whisker • Obj: I can find measures of variability using box and whisker • Step one in making a box and whisker plot: Order the data and find the smallest value, first quartile, median, third quartile and the largest value 22,17,22,49,55,21,49,62,21,16,18,44,48,40,33,45
Step 1 16,17,18,21,21,22,22,33,40,42,44,45,48,49, 49,55,62 Identify the smallest value: 16 First quartile: is the median of the first 8 numbers=21 Median of the group: 40 Third quartile: is the median of the second 8 numbers = 48.5 Identify the largest value=62
Step 2 • Draw a number line and plot a point above each value from step 1
