The researcher replicated the above study but wanted to add the presence of a snack for students while they were working through the word problems because the idea was the snacks would help reduce anxiety, thus also leading to less errors. Therefore, there are still font sizes 12 and 14, still font styles as such Times New Roman and Arial, but the snack was added with two levels... "salty snacks" vs. "sweet snacks". Just as in the previous study, everyone was randomly assigned. The number of errors in their answers were again measured. Again, match the statements below with the appropriate answers. Name the design [ Select ] How many treatment conditions are there? [ Select ] How many possible main effects can there be? [ Select ] How many possible interactions can there be? [ Select ]
