It may also be called a center or location of the distribution. Colloquially, measures of central tendency are often called averages. The term central tendency dates from the late 1920s. From the above explanation we can say that average is a single value that represents a group of values. It depicts the characteristic of the whole group. The value of average lies between the maximum and minimum values of the series.

Some notation. Before we calculate the mode we need to know the following notation (this will also be useful for calculating the mean, variance, standard Illustrated definition of Measure Of Central Tendency: Any of several methods used to find a central value of two or more numbers. Mean, median and mode are Measures advantages and disadvantages measures central tendency is a critical decision making criteria for several elements in Six Sigma.

each of these three measures can tell us what is typical about a distribution of cases; Geometric mean, as another measure of central tendency is very much useful in social science and business related problems. It is an average which is most suitable when large weights have to be assigned to small values of observations and small weights to large values of observation. Measures of central tendency (mean, median, and mode) and dispersion (variance, standard deviation, and range) characterize the probability distribution. A histogram visualizes the distribution of numerical data, indicating the number of data points that lie within a range of values.
