Answer to Question 1

ANS: B, F
A research design is a blueprint for maximizing control over factors that could interfere with a study's desired outcome. The choice of research design depends on the researcher's expertise, the problem and purpose for the study, and the desire to generalize the findings. This means that other research in the area must be taken into consideration as well.

Answer to Question 2

ANS: A, F
Correlational research examines a linear relationship between two or more variables and determines the type (positive or negative) and degree (strength) of the relationship. The strength of a relationship varies from 1 (perfect negative correlation) to +1 (perfect positive correlation), with 0 indicating no relationship. The positive relationship indicates that the variables vary togetherthat is, the two variables either increase or decrease together. The negative or inverse relationship indicates that the variables vary in opposite directions; thus, as one variable increases, the other variable decreases.
