Question

An experiment was planned to study the effect of Sulphate, Potash and Super Phosphate on the yield of potatoes. All the combinations of 2 levels of Super Phosphate [0 cent (p0) and 5 cent (p1)/ acre] and two levels of Sulphate and Potash [0 cent (k0) and 5 cent (k1)/acre] were studied in a randomised block design with 4 replications each. The (1/70) yields [lb per plot = (1/70) acre] obtained are given in table below:

The experiment aims to analyze the effect of different levels of Super Phosphate, Sulphate, and Potash on the yield of potatoes. The data from the randomized block design (RBD) with four replications for each treatment combination is provided. To assess the data, we will use statistical analysis techniques, such as analysis of variance (ANOVA), to determine the significance of each factor and their interactions in influencing potato yield.

### Step 1: Organize the Data
The data presented in the problem can be organized in a table format, representing the different treatment combinations and corresponding yields in pounds per plot.

| Block | Super Phosphate (p) | Sulphate and Potash (k) | Yield (lbs per plot) |
|-------|---------------------|-------------------------|----------------------|
| I     | p0                  | k0                      | 23                   |
| I     | p1                  | k0                      | 25                   |
| I     | p0                  | k1                      | 22                   |
| I     | p1                  | k1                      | 38                   |
