Each of the measures of central tendency have their own advantages/disadvantages.The mean uses all of the data but can be skewed by extreme values. There are three main measures of central tendency: mean, median, and mode. In order to calculate median one has to arrange the numbers first in ascending order and then find the middle value from that series of numbers. If we calculate the mean, median and mode using the data from a sample, the results are called the sample mean, sample median and sample mode. Some pros and cons of each measure are summarized below. The term “number crunching” is used to illustrate this aspect of data description. Takes account of all values to calculate the average. SD is the square root of sum of squared deviation from the mean divided by the number of observations. In simple words, it refers to that value which comes the highest number … While measures of central tendency are used to estimate "normal" values of a dataset, measures of dispersion are important for describing the spread of the data, or its variation around a central value. The median is the middle score for a set of data that has been arranged in order of magnitude. A conceptual understanding of measures of central tendency is basic to understand many aspects of educational measurement and thus essential for inclusion in this resource book.

For the continuous data, test of the normality is an important step for deciding the measures of central tendency … Median is a measure of central tendency which is used to calculate the middle value of series of numbers. Name three measures of central tendency. Measures of dispersion – variance, standard deviation and coefficient of variation for grouped data. In what situation should we use each one of these measures? You can use quantitative research methods for descriptive, correlational or experimental research. Disadvantages: It is very time-consuming and the harmonic mean (H.M.) forms an important measure of the central tendency of data. Lends itself to computation of other stable Measures. a) The mean of the salaries is calculated by adding up each individual salary and dividing it by the seven employees. CVP is widely believed to indicate general intravascular volume status of the patient. Advantages and Disadvantages of Mean as a Measure of Central tendency • The Most Common Measure of Central Tendency and easy to calculate • The mean uses every value in the data and hence is a good representative of the data set.
