Median Another measure of central tendency is the median, which is defined as the middle value when the numbers are arranged in increasing or decreasing order. These measures tell us where most values are located in distribution and are also known as the central location of the distribution.Sometimes the data tends to cluster around the central value.

Note that for datasets that follow a normal distribution, the mean, median, and mode MODE Function The MODE Function is categorized under Excel Statistical functions. 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. The measures of central tendency can be found using a formula or definition. Unit-II MEASURES OF CENTRAL TENDENCY AND DISPERSION = 1 5 +0.6021 0.7782 + 90318451 1 5 4.8098 = 0.962 = 100.962 = 9.1622 Harmonic mean: The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals. The measures of dispersion is important to compare uniformity, consistency and reliability amongst variables / series. In layman's terms, central tendency is nothing but 'average'. 1.1 - Measures of Central Tendency; 1.2 - Measures of Dispersion; 1.3 - Measures of Association; 1.4 - Example: Descriptive Statistics; 1.5 - Additional Measures of Dispersion; 1.6 - Example: Generalized Variance; 1.7 - Summary; Lesson 2: Linear Combinations of Random Variables A measure of central tendency is also known as a summary statistic and it generally represents the central point of the data set. Measures of Central Tendency. Central Tendency . 4 and Dispersion. When you order the daily earnings shown in Table 1, you get $50, $100, $150, $350, and $350. Dispersion is a measure of the variation of the items from central value. CHAPTER 15 – UNIT 1 – MEASURES OF CENTRAL TENDENCY Chapter 15 – Measures of Central Lecture 8: Measures of Dispersion Lecture 9: Assumptions for Measures of Central Tendency/ Measures of Dispersion Descriptive Statistics: Measures of Central Tendency and Cross - tabulation Introduction Measures of central tendency (MCT) allow us to summarize a whole group of … Points to remember. Also, they can be identified using a frequency distribution graph. There are three measures of central tendency – the mean, the median, and the mode. It is important to note that the choice of which measure of central tendency (and its associated measure of dispersion) depends on the type of data and its distribution. Totaling all the measures and dividing by the number of measures, you get $1,000 ÷ 5 = $200. And, dispersion helps in evaluating how near or far the other values are from this average value. Measures of central tendency and dispersion 1. In this chapter, you can learn • how the values of the cases on a single variable can be summarized using measures of central tendency and measures of dispersion; • how the central tendency can be described using statistics such as the mode, median, and mean; • 4.1 Central Tendency.
