Perform a one-way independent -samples ANOVA test to determine:
1- what is the value of the mean square for error (the "within groups" mean square) that would be reported in the ANOVA test

2- What is the value of the mean square for treatments (the "between groups" mean square) that would be reported in the ANOVA test

#### Solution Preview

I have taken random values and shown calculations in excel file.

This is the simplest way to calculate.

Following are the steps for calculations .

1) Calculate the correction factor. It is given by ( &#8721;yij )^2 / number of values
For the values in excel file correction factor is given by 388*388 / 17 = 8855.529412

2) Treatment sum of squares is given by &#8721; ( Yi.)^2 / ni - Correction factor calculated in step 1
For the values in excel file ...
