So, you have the liberty of either using the F value or the p value. But if you are doing you calculation manually using F value is more simpler, if you are using a software then p-value is simpler.

WebThe high F-value graph shows a case where the variability of group means is large relative to the within group variability. In order to reject the null hypothesis that the group means are equal, we need a high F-valu. Low f value is equal to high p value You want to look for results with high f value and low p value. Web3 de nov. de 2024 · This is a standard one-factor ANOVA with three levels of the factor. Because the sample means are quite different and the sample standard deviations are relatively small, it turns out that the F-statistic is very large, which makes the P-value essentially 0. (Computations from Minitab 17; format slightly edited for brevity.)
WebThe F ratios are not very informative by themselves, but are used to determine P values. P values. Two-way ANOVA partitions the overall variance of the outcome variable into three components, plus a residual (or error) term. Therefore it computes P values that test three null hypotheses (repeated measures two-way ANOVA adds yet another P value).
