Answer to Question 1

ANS: D
Operationalizing a variable or a concept involves developing conceptual and operational definitions. A conceptual definition provides the theoretical meaning of a concept or variable. The conceptual definition provides a basis for formulating an operational definition. An operational definition is derived from a set of procedures and progressive acts that a researcher performs either to manipulate an independent variable or to measure the existence or degree of existence of the dependent variable.

Answer to Question 2

ANS: A
A hypothesis is a formal statement of the expected relationship or relationships between two or more variables in a specified population. The null hypothesis, also referred to as a statistical hypothesis, is used for statistical testing and interpretation of statistical outcomes. The null hypothesis can be simple or complex and associative or causal. The null hypothesis states that there is no relationship between two or more variables. Extraneous variables exist in all studies and can affect the measurement of study variables and the relationships among them. The extraneous variables that are not recognized until the study is in process, or that are recognized before the study is initiated but cannot be controlled, are referred to as confounding variables. Research objectives are clear, concise, declarative statements that are expressed in the present tense, focus on one or two variables (or concepts), and indicate whether the variables are to be identified or described. A research question is a concise, interrogative statement that is worded in the present tense and includes one or more variables (or concepts).
