The displacement of each combined treatment mean for Factor A from the grand mean shown by the arrows is caused by the average effects of that treatment, plus ponds nested within each treatment, plus error.

The number of degrees of freedom will be one less than the number of treatments, so in this example with two treatments there is one degree of freedom.. 13.6 A pictorial explanation 120 Weight 105 90 70 55 40 Prawn food + vitamin A Prawn food only Figure 13.9 Estimatio n of the effect of Factor B(A). The displacement of each cell mean from its treatment mean is shown by each arrow and is caused by the average effect of that subgroup (each pond) plus error.

The number of degrees of freedom will be the sum of one less than the number of ponds within each treatment. In this example there are two degrees of freedom..

The displacements of EAN-13 Supplement 5 for .NET each treatment mean from the grand mean are squared, multiplied by the number of replicates within their respective treatment, and added together to give the sum of squares for Factor A, which will include treatment, plus subgroups(treatment), plus error. The number of degrees of freedom is one less than the number of treatments, and dividing the sum of squares by this number will give the mean square for Factor A (i.

e. treatment plus subgroups(treatment), plus error). Third, a mean is also calculated for Factor B(A), which is the variation contributed by each subgroup (in this case each pond) (Figure 13.

9). Each subgroup mean will only be displaced from its respective treatment mean by the effect of the subgroup plus error. The displacements are squared, multiplied by the number of replicates within their respective subgroups and added together to give the Factor B(A) sum of squares.

The number of degrees of freedom will be the sum of one less than the number of subgroups within each treatment. Dividing the sum of squares by this number will give the mean square for Factor B(A) (i.e.

subgroups plus error).. Two factor analysis of variance without replication Table 13.5. The appro .

Source of variation F actor A (treatment). Factor B(A) + error ________________ error The procedures shown in Figures 13.7 to 13.9 give three separate sums of squares and mean squares: (a) Factor A: treatment + subgroups(treatment) + error (Figure 13.

8) (b) Factor B(A): subgroups(treatment) + error (Figure 13.9) (c) error (Figure 13.7) and no other mean squares are needed to isolate the effects of the treatments from the subgroups nested within each treatment.

First, to isolate the effect of treatment only, the MS for treatment plus subgroups(treatment) plus error is divided by the MS for subgroups(treatment) plus error. Second, to isolate the variation due to subgroups(treatment), the MS for subgroups(treatment) plus error is divided by the MS error (Table 13.5).

In the example shown in Figures 13.7 to 13.9 the F ratio for the effect of Factor A will only have one and two degrees of freedom, despite there being 16 prawns in the experiment.

This is appropriate because the level of replication for this comparison is the ponds rather than the prawns within each pond. Most statistical packages will do a nested ANOVA and the results will be in a similar format to Table 13.6, which gives the results for the data in Table 13.

4. If the treatment factor is fixed and significant, you are likely to want to carry out a-posteriori testing to examine which treatment means are.
