Measurement of Central Tendency I
This is a measure of how the data are centrally placed. Depending on the information required, the three commonest measures of position are the arithmetic mean, median, and mode. Mean is the most widely used measure and sometimes called the arithmetical average. The mean of the number x1, x2, x3, x4 ............ xn
X = ∑x/n, where ∑x is the sum of all items. n = number of items.
When the data involves frequency; mean = ∑fx/∑
