Step-by-Step Guide to ANOVA Table Calculation: CRD Design with Equal Replications

In this video, we will walk you through the step-by-step process of constructing the ANOVA table for a completely randomized design experiment with equal replications. The experiment tested the effects of three fertilizer formulations (A, B, and C) on the yield of corn using a pot experiment. Each treatment was repeated four times, and the yields are listed in the table provided. We will start by expressing the claim and creating a null hypothesis. The claim is that at least one fertilizer formulation differs significantly from the others. Then, we will calculate the correction factor and the sum of squared total, which will help us fill out the ANOVA table. Through this ANOVA table calculation, we will determine if the differences in the mean yields of the fertilizer formulations are significant or if they are due to random chance. By the end of the video, you will have a solid understanding of how to construct an ANOVA table and interpret the results.
