A measure used to summarise numerical data and describe how ‘spread-out’ a set of measures (or values) are from the average. For example, the average height of a group of schoolchildren can be calculated using the total of all their heights added together and then divided by the number of schoolchildren in the group. Standard deviation measures the ‘spread’ of those heights. So, in the example it tells you whether all those in the group were about the same height, or whether some were very tall and some were short.
