Key learning points
- Statistical summaries can be compared to graphical representations of data.
- Statistical summaries can be used to produce a sketch of what the graphical representation could be.
- Different statistical representations can help form a more complete picture.
Keywords
Statistical summary - A statistical summary sums up the features of a data set. It may contain the averages (mean, median, mode). It may also contain the range.
Central tendency - is a summary measure that attempts to describe a whole dataset with a single value that represents the middle or centre of its distribution.
Spread - The spread/dispersion of data values describes how far apart the pieces of data are.
Common misconception
The mean and median will always be close to the most frequent values (or peaks) in a dataset.
The mean and median may be at the lower or lowest frequency parts of a distribution. This is especially likely if the data is bimodal.
