each of the 25 cells of the design. How many degrees of freedom will there be for the

row-column interaction effect?

**Thought that there was no row-column interaction in latin square??? Is it t-1=4??**

For a replicated 5x5 Latin square design where there are two observations in

each of the 25 cells of the design. If the row, and column main effects, and the rowcolumn

interaction effect are tested, how many degrees of freedom will remain for the

error term?

**Is it (t-1)(t-2) = 4 * 3 = 12?????**

Am not to sure if either are correct...
