Unit 4 Descriptive Statistics Pdf Skewness Quartile Central tendency can be measured by mode, median, or mean; measures of dispersion, such as standard deviation and coefficient of variation can also be calculated from ratio scales. 3.2.3 coefficient of variation (cv) the coefficient of variation is the ratio of standard deviation to the arithmetic mean expressed as percentage. cv can be used to know the consistency of the data. a distribution with smaller cv is more consistent than the other one. In this chapter, you will study numerical and graphical ways to describe and display your data. this area of statistics is called "descriptive statistics." you will learn how to calculate, and even more importantly, how to interpret these measurements and graphs. Measure of dispersion, helps compare variation across variables with different units. a variable with higher coefficient of variation is more dispersed than one with lower cv. cv works only with variables with positive values.
Lec 1 Descriptive Statistics Pdf Coefficient Of Variation In this chapter, you will study numerical and graphical ways to describe and display your data. this area of statistics is called "descriptive statistics." you will learn how to calculate, and even more importantly, how to interpret these measurements and graphs. Measure of dispersion, helps compare variation across variables with different units. a variable with higher coefficient of variation is more dispersed than one with lower cv. cv works only with variables with positive values. Provides some easy to use functions and classes to calculate variability measures such as coefficient of variation with confidence intervals provided with all available methods. Summary measures describing a population, called parameters, are denoted with greek letters. important population parameters are the population mean, variance, and standard deviation. which measure to choose? the mean is generally used, unless extreme values (outliers) exist. Quartile deviation is a better measure of dispersion than range because it takes into account 50 percent of the data, unlike the range which is based on two values of the data, that is highest value and the lowest value.
