Keywords
Statistical summary - A statistical summary sums up the features of a data set.
Spread - The spread/dispersion of data values describes how far apart the pieces of data are.
Central tendency - a summary measure that attempts to describe a whole set of data with a single value that represents the middle or centre of its distribution
Common misconception
Either the mean, median or mode could be used as an average in any situation.
The choice of average can depend on the type of data. For example, in a list of colours, you can find the mode but not the mean.
