Considering the concepts discussed in the provided outline, describe a counseling-related scenario that illustrates the presence of independent, dependent, and confounding variables, as well as potential sources of bias. Explain how these variables and biases could influence the interpretation of research results. Additionally, discuss strategies that a researcher in such a counseling-related scenario might employ to control for confounding variables and address sources of bias to ensure the validity of the study.

Fundamental vs. Applied Research
Fundamental research.
Applied research.

LO 2.1: Choose a research topic.
Key point: Determining a topic of interest.
Fundamental research: looks at the world at large and tries to generate new ideas or explanation about how the world works and why; may not have application in everyday life in the immediate sense.
Applied research: seeks to solve a specific societal problem or uncover more information about a particular issue; has direct implications in practice.

Selecting Your Research Topic
(2 of 4)
Narrowing the Research Topic
Consider constructs and population of interest.
Construct.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
3
LO 2.1: Choose a research topic.
Two features of a broader topic can lead to the research question: the constructs and the population of interest.
Construct: a concept that is possible to measure in a form.

Operationalization of Constructs

Operationalization.
Variable.
Conceptualization.

6
LO 2.2: Explain how to operationalize research constructs.
Key point: Formulating a research question.
Operationalization: turning constructs into actual variables to measure
Variable: a specific feature or aspect of the construct that can take different values for each participant in a study.
Conceptualization: the process of breaking down constructs into smaller pieces and clarifying to know the precise meaning of each.

Types of Variables (1 of 4)
Independent and Dependent Variables
Independent variable.
Dependent variable.
Variables are unique per study.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
8
LO 2.3: Describe the different types of variables.
Key point: Collecting information.
Independent variable: the explanatory or predicting variable that explains the variation in the dependent variable; often constant/doesn’t change for the participant
Dependent variable: the outcome; what researchers want to find out from a study and what they hope is influenced by the independent variable.
Variables are unique to each study; a variable can be dependent in one study and independent in another.

Types of Variables (2 of 4)
Control Variables
Control variables.
Help minimize biases and improve accuracy.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
9
LO 2.3: Describe the different types of variables.
Control variables: any variables that are used to control the results; not directly related to the focus of the study but crucial for understanding the relationship between the variables of focus.
They help minimize biases and provide more accurate findings.
9
Types of Variables (3 of 4)
Confounding and Disturbance Variables
Confounding variables.
Disturbance variables.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
10
LO 2.3: Describe the different types of variables.
Confounding variables: influence the independent variable in such a way that the results from the dependent variable become untrustworthy; could not have been controlled or predicted during the study’s design; only become apparent during data collection or analysis.
Disturbance variable: lurks in the background and disturbs the findings of the dependent variable; common characteristics of participants mislead the findings of the study without the researchers’ awareness.
10
Types of Variables (4 of 4)
Moderators and Mediators
Moderators.
Mediators.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
11
LO 2.3: Describe the different types of variables.
Moderators: variables that can strengthen or weaken an already established relationship between the independent and dependent variables.
Mediators: intervening variables that interfere with the relationship between the main variables; when a mediator is present, the relationship between the independent and dependent variables may not even exist anymore.
11
Types of Hypotheses (1 of 4)
Hypothesis.
Generally present in quantitative study.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
12
LO 2.4: Formulate the various types of hypotheses.
Key point: Answers to the research question.
Hypothesis: a statement that predicts a specific phenomenon or behavior.
They are usually present in a quantitative study but not a qualitative one.
12
Types of Hypotheses (2 of 4)
Alternative Hypothesis and Null Hypothesis
Alternative hypothesis.
Null hypothesis.
Research outcome options.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
13
LO 2.4: Formulate the various types of hypotheses.
Alternative hypothesis: the prediction based on literature and theory about what the testing results will be; i.e., what the variables are expected to look like once the data is collected.
Null hypothesis: claims there is no relationship between the variables of interest in the study; this is the hypothesis researchers are actually testing with their findings.
Research outcomes have two options: reject the null hypothesis in favor of the alternative hypothesis, or fail to reject the null hypothesis.
13
Types of Hypotheses (3 of 4)
Directional Hypothesis and Nondirectional Hypothesis
Directional hypothesis.
Nondirectional hypothesis.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
14
LO 2.4: Formulate the various types of hypotheses.
Directional hypothesis: predicts a specific course for the variables
Nondirectional hypothesis: has no direction and simply predicts a relationship between two or more variables; rather than making assumptions on how the variables will behaving, researchers are investigating the possible relationship between variables.
14
Types of Hypotheses (4 of 4)
Open-Ended Question
Used with qualitative studies.
Qualitative studies use different methodologies.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
15
LO 2.4: Formulate the various types of hypotheses.
For qualitative studies rather than quantitative; i.e., when the researcher has many constructs but is not attempting to measure them
A qualitative study asks different types of research questions and has a different methodology to collect data.
15
Visualizing a Research Question
(1 of 3)
Try drawing the research question.
Pajo, Introduction to Research Methods: A Hands-on Approach, 2nd Edition. © 2023 SAGE Publishing.
16
LO 2.5: Create a visualization of a research question.
Key point: Planning a study.
It can be helpful to make a drawing of the research question to help visualize it.
