Explanation / Answer

Result:

This is a Randomized block design. We have to reduce the experimental error among observations of the same treatment by accounting for the differences among blocks. So this is not one way ANOVA.

Chi square test is used for the two way table of frequencies. Chi square test is not applicable for this given data because the given numbers are continuous score for each treatments.
