Presentation Transcript

  1. Choosing the best average Each of the 3 types of average has a specific use, and should be used for it only.

  2. The Mode • The Mode is used when you want to find things like: • What colour do most people like? • This is usually the case when you are looking at data which is not numerical, e.g. items (CDs, Shoes, Books)

  3. The Median • The Median is used when you want to find a typical value for a data set that is very spread out. • E.g. the results for a year 7 form in maths before being set. • The Mean • The Mean is used when you want to find the typical value for a data set that is NOT that spread out, such as individual maths sets.
