Set of data - A set of data is collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.
Common misconception
The mean average is used to compare different sets of data. Much of the data we see in the media uses mean average values so it is important to know how these figures are calculated.
Discuss what the mean average of a set of data represents and perhaps look at current news stories or local papers for examples of the mean average used in the media.
