Lesson details
Key learning points
- Data can be hard to compare when presented in lists and tables.
- Statistical summaries can be calculated to compare data sets.
- Statistical summaries do not always provide enough information by themselves.
Keywords
A statistical summary - sums up the features of a data set. It may contain the average (mean, median and/or mode) which measures the central tendency. It may also contain the range which measures the spread.
Common misconception
Pupils may feel that one statistical summary is enough to compare two data sets.
Highlight to pupils that the more information you know, the better your understanding of a data set and therefore a more comprehensive comparison can take place. Compare the means of {-120, -100, -50, 0, 1000} and {145, 145, 146, 147, 147}.
