One Way Anova Table Value. R number of rows. Anova table is a tabular form of all the data and calculations performed during the test.
An f value appears for each term in the analysis of variance table. A tukey post hoc test revealed significant pairwise differences between fertilizer types 3 and 2 with an average difference of 0 42 bushels acre p 0 05 and between fertilizer types 3 and 1 with an average difference of 0 59 bushels acre p 0 01. Numerator degrees of freedom treatments 1 t 1 3 1 2 denominator degrees of freedom total observations minus treatments n t 12 3 9.
Excel will generate the p values for you.
The one way anova is useful when we want to compare the effect of multiple levels of one factor and we have multiple observations at each level. Since this p value is not less than 0 05 we fail to reject the null hypothesis. In the anova table the p value is 0 031054. To get a more exact cut off use excel to run the anova.
