Mean, median, and mode are the measures of central tendency, used to study the various characteristics of a given set of data. If a data set is symmetric, then both the median and the mean of the data set coincide with each other. An essential statistical concept is the "measure of central tendency". The range offers us a good indication of how dispersed the data is, but we need other measures of variability to discover the dispersion of data from central tendency measurements.

Central tendency is a statistical measure that defines the center of a distribution and is most typical, most representative, of the scores that comprise the distribution of the variable of interest. Central tendency is also useful when you want to compare one piece of data to the entire data set. CLEAR YOUR CONCEPTUAL DOUBTS ON MEASURES OF CENTRAL TENDENCY. Three familiar measures of central tendency are the mean, the median, and the mode. a) Mean b) Median c) Mode Median, because the outlier of 10 would make the average lower, and the mode of 200 would represent the lower data.
