Histogram (non grouped data)
Box and Whisker Plot
Number of values
What difference would it make if the histogram used grouped data?
Label the box and whisker plots below with year level and sex. For some hints you will need to refer to data in the histograms.
Hints: The modal foot length for year 9 boys is 25cm.
More year 9 girls were in the lower range than higher range (positive skew).
Year 6 girls did not have the smallest range.
Write a short description of how foot length changes from Year 6 to Year 9.
