Task One:
The following charts show the foot lengths of boys or girls in years 6 and 9. Draw a line to match each histogram with its box and whisker plot.
Task Two:
Show with a tick whether each statistical characteristic is indicated in the display.
Characteristics
Histogram (non grouped data)
Box and Whisker Plot
Minimum
Maximum
Mean
Median
Mode
Range
IQR
Possible Outliers
Skew
Number of values
What difference would it make if the histogram used grouped data?
Task Three:
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.
