, The mean

 The mean is the arithmetic average of a group of numbers.
 The mean equals the sum of all the scores divided by the number of
scores.
 The trimmed mean - One useful way of reducing the influence of
extreme scores (also called outliers) is to exclude the highest and
lowest scores before calculating the mean. This is known as a trimmed
mean.
 Data entry errors are commonly responsible for outliers in a dataset.
A noticeable difference between the ‘ordinary’ and the trimmed mean
can be an indication that such errors have occurred.
