Measures that indicate the way in which a distribution is spread out are called measures of variability or measures of dispersion. The everyday word for a measure of central tendency is “average”. The mode is the simplest and crudest index of central tendency: it is simply the peak, or ...
Central tendency is a descriptive summary of a dataset through a single value that reflects the center of the data distribution. Along with the variability (dispersion) of a dataset, central tendency is a branch of descriptive statistics. The central tendency is one of the most quintessential conc...
Measures of Central Tendency Unit 3 Sections 3-2 – Day : Properties and Uses of Central Tendency The Mean One computes the mean by using all the values of the data. The. Summarizing Scores With Measures of Central Tendency Central Tendency. Ibrahim Altubasi, PT, PhD The U...
The mean of a set of scores is computed by adding up all the scores and dividing the result by the number of scores. In symbols, X = 危XN, X is the sample mean, 危X is the sum of the X scores, and N is the total number of scores. This chapter illustrates computation from a ...

The organisation of data into class intervals, and hence into a frequency distribution, is only a preliminary step towards a definite quantitative treatment. The frequency distribution with its graphic representations may adequately represent the status of the data, but it does not enable concise and...
Chapter 3 Measures of Central Tendency Three statistics: Mode, Median, Mean Mode median, and mean are three different statistics. They report three different kinds of information and will have the same value only in certain specific situations. ...
Themedianis another frequently used measure of central tendency. The median is simply the midpoint of the distribution, i.e. there are as many numbers above it as below it. If the number of data points is odd, then the median is simply the middle number. Therefore the median of 3, 5...
