Analysis of Variance ANOVA

FIGURE 11.3 One-way ANOVA (analysis of variance). One-way analysis of variance of basal rates of metabolism in melanophores (as measured by spontaneous dispersion of pigment due to G,.-protein activation) for four experiments. Cells were transiently transfected with cDNA for human calcitonin receptor (8 j-ig/ml) on four separate occasions to induce constitutive receptor activity. The means of the four basal readings for the cells for each experiment (see Table 11.4) are shown in the histogram (with standard errors). The one-way analysis of variance is used to determine whether there is a significant effect of test occasion (any one of the four experiments is different with respect to level of constitutive activity). 

The total error has to be calculated here in different way compared with robustness. Whereas in (i) of-A is the variance within a laboratory, o kA is the variance between laboratories plus that within the laboratories, °ijkA = °k + °ijA- The interpretation is analogous to (i), if F < F( a>Vl>V2, then the null hypothesis cannot be rejected and the procedure can be considered as to be rugged. Advantageously, the test can be carried out by schemes of ANOVA (analysis of variance) as given in Sect. 5.1.1. 

ANOVA (Analysis of Variance) A statistical procedure that is used (a) to test for significant differences among means of several sets of results or (b) to estimate variances of several influences operating independently. 

ANOVA (ANalysis Of VAriance) provides a formal statistical procedure for analyzing the data arising from the experimental design used here (Table 3).

Effect of preconditioning on migration results. The effects of preconditioning and of migration test water were investigated using multifactor ANOVA (analysis of variance). This statistieal tool breaks the variability of data (pH, Al, Ca or K) into contributions due to various factors (preconditioning conditions and CO2 added in test water).
