the middle value of a data set when the data is sorted (in a set with an even number of data points, you take the 2 middle ones and divide by 2). For example, if you consider the incomes 30k, 35k, 40k, 45k, 50k, 100k, 200k, the median is 45k, which is more representative of a ‘typical’ salary because it is not skewed upwards by the very high incomes.
