BOX AND WHISKER PLOTS
TASK (GRADE B)
1) A box and whisker plot was made for some data. Find the median, lower quartile,
upper quartile, the minimum, the maximum and range for the data.
Minimum = 35
LQ = 42
Median = 49
UQ = 54 Maximum = 57
2) Make a box plot for the following sets of data:
(a) Initial weights (February) of 14 women in a weight loss study (in pounds):
189 176 186 200 204 188 175 179 188 190 199 194 187 195
(b) Weights of the same women one month later (March):
186 172 180 190 195 179 173 177 180 187 187 190 184 190
(c) Weights of the same women two months later (April):
180 166 175 183 189 177 170 171 170 184 188 182 180 185

Which ones are you using?
1)Compare the data in question 2 (a) and (c) from the task.
(a) How did the median change?
(b) How did the maximum weight change?
(c) How did the minimum weight change?
(d) How did the range change?
(e) How would you judge the effectiveness of the weight loss method used in the study?
2) The box and whisker plots below show car sales of two car salespersons. They have
each recorded the number of sales made each month, over the past 12 months.
(a) Make 3 comments about Carl’s sales figures compared to Angela’s sales figures.
(b) From looking at the box and whisker plots, who do you think is the best car
salesperson, and why?

What have you learnt?
Draw your brain
In your brain, write or draw everything you can remember about
accurately drawing box and whisker plots. It can be a skill or a reflection,
or something else that might be prominent in your brain.
