We have just added a stem and leaf diagram video worked example to our GCSE /IGCSE Statistics Revision Course.

These are the marks of 15 pupils in a test:
4, 17, 15, 22, 8, 13, 28, 15, 12,20, 21, 7, 14, 25, 27 .
Draw a stem and leaf diagram from the marks.

Try this for yourself and then subscribe to see the solution.
