Answer #1

As we know independent variables of two-way ANOVA are called factors. Concept is that there are two variables, factors, which affect the dependent variable say Y. Each of the variable will have two or more level within it and degree of freedom for each level is one minus number of levels.

Here the first factor has 3 levels and the second factor has 6 levels. So there degree of freedoms are 2 and 5 respectively.

That is first factor will have 2 degree of freedom and second one will have 5 degree of freedom.
