We use measures of central tendency because we typically believe that most scores on a scale or responses to an item cluster around the typical or most common score or response in the data set. Consequently, a measure of central tendency is a convenient statistical tool for indicating the most typical score in a set of data. Selecting an appropriate measure of central tendency depends on the measurement scale used to represent a particular variable........... Measures of central tendency identify the middle or centre of a set of data. There are three types: Arithmetic average or mean the total of items or scores in a set divided by the number of individual items in the set. It may give a distorted picture because of large items at either end of the scale. Median the middle item in a range of items (often used in pay surveys when the arithmetic mean is likely to be distorted). Mode the most commonly occurring item in a set of data......... The following are the few requirements to be satisfied by an average or a measure of central tendency: It should be rigidly defined The definition of an average should be clear and rigid so that there must be uniformity in its interpretation by different decision-makers or investigators. There should not be any chance for applying discretion; rather it should be defined by an algebraic formula.........
