Explanation:
From given ANOVA table, it is observed that the p-value for the factor A is given as 0.00 which is less than alpha value 0.05, so we conclude that the factor A is statistically significant. In simple words, there is a significant difference in the two categories of the factor A. There are two levels or categories of factor A as the degrees of freedom is given as 1.
It is also observed that the p-value for the factor B is given as 0.0001 which means the factor B is statistically significant. In simple words, there is a significant difference in the three levels of the factor B. There are three levels as the degree of freedom is given as 2.
The p-value for the interaction between the factor A and B is given as 0.298 which is greater than alpha value 0.05, so we conclude that the interaction due to factor A and factor B is not statistically significant. There is no significant difference observed due to the interaction between given two factors.
