<u>Question 1</u>
The correct answer is: "A randomized block design".
A randomized block design, when conducting an experimental type of research, consists on dividing the whole population into subgroups, also denominated blocks. There is less dispersion in the characteristics of subjects within a block than between blocks. Subsequently, the members of each block are randomly assigned to certain treatments which, in this case, are the different types of advertising to which consumers are exposed.
<u>Question 2</u>
The correct answer is: "The scores on the recall exam".
The aim is to measure the effect of the different advertising campaigns by measuring the subsequent reactions of the participants, which in this case is measured through the recall exam that subjects undertake right after the treatment. Therefore the scores on the recall exam constitute the response or dependent variable that the research aims to explain.
Question 3
The correct answer is: "The type of advertising"
The study aims to quantify the differences registered in the dependent variable, the scores in the recall exams, when subjects have been exposed to different advertising campaings. Therefore the type of advertising constitutes the explanatory variable, whose effect on the dependent variables tries to be assessed.
