Homework Answers
Factorial design is the correct answer because in this research design, indepedent and dependent variables are used which helps us in understanding the effect of change in value of independent variable on the dependent variable.
For example, the effect of studying at night hours on the exam score card.
So, option A is the correct answer.

Classify the experiments according to their experimental designs. Some designs may be used more than once. Vitamins. A sample of 50 children was separated into boys and girls. The members of each group were randomly assigned to two different vitamin supplements. The responses of each child were recorded at the completion of the experiment. Flu. A sample of 50 flu patients was grouped into pairs of similar individuals based on age and...
