Question 1

Which of the following statements accurately characterizes the research process?

Accepted Answer

Each statement accurately characterizes aspects of the research process. It involves several related steps (A), is not standardized across all research types (B), is determined by the nature of the research problem (C), and can be conceptualized as cyclic, often involving revisiting and revising steps based on findings (D).

Question 2

Which of the following does not represent one of the criteria that should be considered in evaluating the appropriateness of a potential research problem?

Accepted Answer

The validity of the null hypothesis is not a criterion for evaluating the appropriateness of a potential research problem. It is a concept used in the context of hypothesis testing within the research process, not for evaluating the suitability of the research problem itself.

Question 3

The statement of purpose in a research proposal is intended to:

Accepted Answer

The statement of purpose in a research proposal is primarily meant to express the goals for the research study, outlining what the researcher aims to achieve.

Question 4

Research questions are often broad and need to be transformed into specific problem statements that are amenable to investigation. Research questions may generally be categorized into the following three basic types of questions:

Accepted Answer

Descriptive questions aim to describe phenomena or characteristics of a subject. Relationship questions explore the connections between variables. Difference questions investigate the distinctions between groups or conditions. These categories broadly cover the types of questions researchers might pose to guide their investigations.

Question 5

A characteristic, trait, or attribute of a person, place, or thing that can have more than one value is called what?

Accepted Answer

A variable is a characteristic, trait, or attribute of a person, place, or thing that can vary or have more than one value.

Question 6

All studies have some elements that are beyond the control of the researcher-things that could negatively influence the results and are considered as weaknesses of the study. In research terminology, what are these called?

Accepted Answer

Limitations are factors in a study that the researcher cannot control that may affect the results or how they can interpret the findings. These could include methodological limitations, sample size constraints, or external factors that could impact the study's outcomes.

Question 7

An independent variable is one in which the researcher:

Accepted Answer

An independent variable is the variable that the researcher manipulates to observe its effect on the dependent variable.

Question 8

Another name for the dependent variable is the:

Accepted Answer

The dependent variable is also known as the outcome because it is the variable that researchers are interested in explaining or predicting, and it depends on the independent variable(s).

Question 9

Which of the following is an example of an extraneous variable?

Accepted Answer

Extraneous variables are those that are not the primary focus of a study but can affect the outcome. In this case, extra steps added by participants (C) could influence the results of an obesity study independently of the interventions being tested, making it an extraneous variable.

Question 10

A variable that could affect the direction and strength of the relationship between independent and dependent variables is called the:

Accepted Answer

A moderator variable is one that influences the strength or direction of the relationship between an independent (predictive) variable and a dependent (outcome) variable. It essentially modifies how the independent variable is related to the dependent variable.
