Descriptive statistics measures of central tendency and dispersion

Mean, mode, and median are measures of central tendency because they measure the distribution of data around a central value. Range, standard deviation, maximum value, and the minimum value are measures of dispersion because they indicate the degree of variation of a given data from a central value.Mean, Median and Mode are the three main measures of central tendency and Range. Percentile, variance, standard deviation, standard error and confidence interval are measures of dispersion.Central tendency gets at the typical score on the variable, while dispersion gets at how much variety there is in the scores. When describing the scores on a single variable, it is customary to report on both the central tendency and the dispersion.There are 3 main types of descriptive statistics: The distribution concerns the frequency of each value. The central tendency concerns the averages of the values. The variability or dispersion concerns how spread out the values are.Measures of central tendency and dispersion are vital tools to draw a short interpretation of data. Central tendency and dispersion tools can be defined as finding approximate points in a data set capable of representing the whole sample or data. The main aim of these measures is to give a few values for getting the right conclusion.,The modeis the most frequently occurring value in the dataset. It’s possible to have no mode, one mode, or more than one mode
