Answer to Question 1
ANS: C
Research objectives are clear, concise, declarative statements that are expressed in the present tense. For clarity, an objective usually focuses on one or two variables (or concepts) and indicates whether the variables are to be identified or described. Objectives can also identify relationships or associations among variables, determine differences between groups or compare groups on selected variables, and predict a dependent variable based on selected independent variables.
Answer to Question 2
ANS: D, G
A relational statement declares that a relationship of some kind exists between or among two or more concepts. Relational statements describe the direction, shape, strength, symmetry, sequencing, probability of occurrence, necessity, and sufficiency of a relationship. Researchers usually determine the strength of the relationship between concepts by correlational analysis. The statistic r is the coefficient obtained by performing the statistical procedure known as Pearson's product moment correlation. A value of 0 indicates no strength, whereas a +1 or a 1 indicates the greatest strength, as in the diagram. The + or does not have an impact on strength. For example, r = 0.35 is as strong as r = +0.35. The greater the strength of a relationship, the easier it is to detect relationships between the variables being studied.
