Multivariate analysis of variance Multivariate analysis of variance (MANOVA) is a generalized form of univariate analysis of variance (ANOVA). It is used when there are two or more dependent variables. It helps to answer : 1. do changes in the independent variable(s) have significant effects on the dependent variables; 2. what are the interactions among the dependent variables and 3. among the independent variables.[1] Where sums of squares appear in univariate analysis of variance‚ in multivariate

One-way Analysis of Variance (Abbreviated one-way ANOVA) is a technique used to compare means of two or more samples (using the F distribution). This technique can be used only for numerical data. It consists of a single factor with several levels and multiple observations at each level. With this kind of layout we can calculate the mean of the observations within each level of our factor. The residuals will tell about the variation within each level. It can also average the means of each level

management concluded the large fixed cost absorbed sale figure. First it is important to understand the standard costing system implemented in Rubber group. Standard costing assigns quantity and price standards to each component of variable and fixed costs in calculating the total cost. In the case of NASA‚ the system uses standard purchasing price (input cost) and standard inputs usage in place for variable costs‚ and standard spending price (input cost) and standard
