mean refers to the mean or average that is used to derive the central tendency of the data in question. It is determined by adding all the data points in a population and then dividing the total by the number of points. The resulting number is known as the mean or the average.Thus we have;

1+2+2+2+3+4+5+5 = 24 ÷ 8 = 3
