KS4 Box and Whisker
This list comprises a number of resources for around 4 lessons to cumulate in a good understanding of box and whisker plots.
Before using these resources students should have prior knowledge of data, median, range, mode mean and interquartile range. It would help to understand frequency tables but it could begin at this point also.
The first stage is ‘Understanding Mean, Median, Mode and Range’ a Flash application showing a set of raw scores that are put into a frequency table and the raw scores can be changed. This gives an understanding that when the raw scores become too many then it helps to summarise them in a frequency table. It also shows ways for this data to be displayed. A lesson plan is included with recording sheets for pupils who then complete the display of the statistical results.
The second stage is ‘Interpreting bar charts, pie charts, box and whisker plots’ with a Flash application that extends the first section. The teacher inputs the raw scores for a frequency table and pupils record this on a record sheet. This is displayed in a bar chart, pie chart, mean etc as well as a box and whisker plot.
A lesson plan is included with recording sheets for pupils who then complete the display of the statistical results. The teacher can hide the box and whisker plot until pupils have finished allowing self marking.
Interquartile range can be supported with ‘Handling Data’ that contains an information sheet for any pupils who need support for interquartile range and the links to the various parts of a box and whisker plot.
A worksheet is provide via ‘Box and Whisker Worksheet’ for pupils to complete and works in conjunction with the information sheet.
