MEAN, MEDIAN, MODE AND RANGE, INTER-QUARTILE RANGE

This lesson focuses on different types of averages, the location and spread of data, and the pro's and con's of each. The power point uses a case study to help explain how mean, median, mode, range and inter-quartiles are calculated, and what each type of statistic shows. This lesson is designed to be interactive, with questions/ answers included. This also reduces the need for printing. Although originally designed for GCSE, this resource will prove useful in any math lesson. Learning aims are also included so students can measure their level of understanding and success in class. A lesson I have enjoyed teaching myself!
