Comparing Datasets - Written Answers

To write comparisons of two data sets look at different statistical measures and compare the values between the two datasets: mean, mode, median, range, interquartile range, quartiles, outliers...

Method

Method

Write a comment for each value you consider, stating whether it is roughly the same for each data set or whether they are different.
Make sure the comments are in context with the dataset.

Question

Question

The box plots above give times for Year 10 and Year 11 students to run a race. What could we say about these data sets?

Answer

Answer

The Year 10s had a median of just over 14 seconds whereas the Year 11s had a median of just over 16 seconds so the Year 10s ran quicker on average.
The Year 10s data has a larger interquartile range and a larger total range so their times are more spread out that the Year 11s.
