6 Summary
Analysing data using averages is one method of finding out more about data, in this case a typical value. Averages and ranges are the bases for the study of statistics, which provides many powerful tools to look more deeply into data sets. Statistics are used by many different people and in many different professions, but they are particularly important to anybody who collects data – if you don’t have any tools to analyse information, the data is not much good on its own! Presenting data clearly in an ordered table is also a very useful skill to have. This allows you to communicate with others clearly and is used in a range of other academic study areas.
Congratulations for making it to the end of this week! You should now be able to:
- calculate the average for a set of data using the mean, median and mode
- calculate the range of a set of data
- understand that different averages may give different results for the same set of data
- read and construct tables.
You can now go to Week 8.
