Using the table, we have to find the Sum of Squares Error

Data for weights of men Calculate Sum of Square Error for the above data, using the one-way ANOVA Data Analysis tool in Excel

In Excel, Click on the Menu Item Data-> Data Analysis

In Data Analysis, Click on Anova: Single Factor, enter the Input Range, Click on Grouped by Columns, and Click Ok

As part of an experiment to see how different types of soil cover would affect slicing tomato production, Marist College students grew tomato plants under different soil cover conditions. Groups of three plants each had one of the following treatments

• bare soil

• a commercial ground cover

• black plastic

• straw

• compost

All plants grew under the same conditions and were the same variety. Students recorded the weight (in grams) of tomatoes produced by each of the $n=15$plants:

Bare:${n}_{1}=3$ | Ground cover:${n}_{2}=3$ | Plastic:${n}_{3}=3$ | Straw:${n}_{4}=3$ | Compost:${n}_{5}=3$ |

2625 | 5348 | 6583 | 7285 | 6277 |

2997 | 5682 | 8560 | 6897 | 7818 |
