It shows how to estimate numbers above 160 cm from a total of 60 students (finding 48 at 160 cm or less, so 12 above), explains constructing box plots from five-number summaries and interpreting quartiles and medians, and uses box plots to compare distributions (including median and range). It also covers probability from repeated trials and two stage situations, including an example where the probability of landing up then down is 2/9, and tree or table based probability calculations such as 1 minus 0.85 squared equals 0.2775. Additional worked examples include frequency polygon midpoint methods and using cumulative frequency graphs to estimate probabilities and median and interquartile range."}
