PPT-ANALYSIS OF VARIANCE

In this Lecture we study whether changes in the independent variables cause changes in the mean response and we analyze the data using a method known as analysis of variance . True function is y = f(x) + True function is y = f(x) + Standard cost is the pre determined cost which determines in advance what each product or service should cost under given circumstances..

Some Review and Some New Ideas. Remember the concepts of variance and the standard deviation…. Variance is the square of the standard deviation. Standard deviation (s) - the square root of the sum of the squared deviations from the mean divided by the number of cases. .

The mean is the numerical average of the data set, and we use the mean to describe the data set with a single value that represents the center of the data. Many statistical analyses use the mean as a standard measure of the center of the distribution of the data.. Yoni . Nazarathy. *. EURANDOM, Eindhoven University of Technology,. The Netherlands..

Population mean . gives no idea about the phenotypic values recorded on different individuals whether values are same or different.. If values are same or similar, then population mean also will be the same. If values are different from individual to individual then population mean cannot tell about the distribution of values around the central value, the population mean.. ANOVA is comparison of means. Each possible value of a factor or combination of factor is a treatment.. The ANOVA is a powerful and common statistical procedure in the social sciences. It can handle a variety of situations..
