Simplest measurement of dispersion
Webb• Measures of dispersion or variability are measures of individual differences of the members of the sample o They give indication of how scores in a sample are dispersed … Coefficient of variance ( CV) is the measure of dispersion which is independent of mean. It is a useful tool for comparison of dispersion of two different variables as it is independent of mean and unit of observation. It is given by: CV=\frac {SD} {\overline {x}}\ast 100 (Formula 8.13) Visa mer It is also known as root mean square deviation. For smaller samples (less than 20 observation/data points), the formula is as below: Visa mer In statistics the entity Σi(xi − x¯)2 is known as second moment, similarly Σi(xi − x¯)3 is known as third moment which is utilized in calculation of skewness of data and Σi(xi − x¯)4is known as … Visa mer The entity Σi(xi − x¯)2is known as sum of squares. The sum of squares for more than one series has been described in Chap. 13. Σi(xi − x¯)2can be written as Hence the alternate … Visa mer
