There are two ways to use the null sampling distribution of F in one-way ANOVA: to calculate a p-value or to find the “critical value” (see below). A close up of the HSD test.

21 Sep 2011 The following table shows how ANOVA differs from other types of regression At the heart of every type of ANOVA lies the F-value. Whenever
This article is about how to interpret the results of Anova, including P-value, and connect it to our action. In order to understand P-value, you have to understand the concept of 'Null Hypothesis'. This article explains the P-value and Null Hypothesis visually easy to understand manner.

$\begingroup$ In all parametric statistics there is a direct functional link between the test statistic (F in this case) and the p-value. These have been put into table for convenience, but can also be computed directly. You can either use alpha to find the cut-off for a critical region to compare the test statistic to (which I think is more intuitive) or use the computed test statistic to Table of critical values for the F distribution (for use with ANOVA): How to use this table: There are two tables here. The first one gives critical values of F at the p = 0.05 level of significance. If your obtained value of F is equal to or larger than this critical F-value, then your result is P-value基本翻译：假定值、假设机率。用SAS、SPSS等专业统计软件进行假设检验，在假设检验中常见到P 值方法( P-Value，Probability，Pr)，这是由于它更容易应用于计算机软件中。 This article is about how to interpret the results of Anova, including P-value, and connect it to our action. In order to understand P-value, you have to understand the concept of 'Null Hypothesis'. This article explains the P-value and Null Hypothesis visually easy to understand manner. An example of finding the p-value in one-way ANOVA. The p-value (the area to the right of the F test statistic) is found using both the F table and the statistical software R. Use the p-value in the ANOVA output to determine whether the differences between some of the means are statistically significant. To determine whether any of the differences between the means are statistically significant, compare the p-value to your significance level to assess the null hypothesis. The null hypothesis states that the (6) P means "the P-value." Now, let's consider the row headings: (1) Factor means "the variability due to the factor of interest." In the tire example on the previous page, the factor was the brand of the tire. In the learning example on the previous page, the factor was the method of learning.
If your one-way ANOVA p-value is less than your significance level, you know that Use the grouping information table and tests for differences of means to Construct the ANOVA table (by hand or by using a TI-83, 83+, or 84+ calculator), find the p-value, and state your conclusion. Use a 5% significance level. The results of the ANOVA are presented in an ANOVA table, which has columns These F-ratios are called Fcrit values and may be found with the Probability This is the table that shows the output of the ANOVA analysis and whether there We can see that the significance value is 0.021 (i.e., p = .021), which is below Values of F, for p = 0.05, Back to one-way ANOVA? Back to two-way freedom are shown. If you want an intermediate value, use the next lowest in the table.
