Which of the following is an example of a categorical variable?

In psychological research, categorical variables are used to classify individuals into groups based on qualitative labels. Match each variable name with the specific example of how it would be measured as a categorical variable.

In a study on peer pressure, a researcher records whether each participant 'conformed' or 'did not conform' to a group's decision. Because this measurement involves assigning a qualitative label to each individual rather than a numerical amount, it is an example of a categorical variable.

In a study evaluating student well-being, a researcher collects data on university major, number of hours spent studying, and whether the student is receiving psychotherapy. To perform a comparative analysis, the researcher must distinguish the qualitative markers from the numerical measurements. By identifying which variables classify individuals into groups rather than representing a numerical amount, the researcher determines that 'university major' and 'receiving psychotherapy' are both ________ variables.

Arrange the steps a researcher should follow to evaluate and justify the validity of classifying a variable, such as 'Psychotherapy Status' or 'University Major', as a categorical variable in a psychological study.

A person's current occupation is considered an example of a categorical variable because it is measured by assigning a descriptive label rather than a numerical amount.

In a survey of college students, a researcher records each participant's 'university major'. Which statement best explains why this is considered a categorical variable?

A researcher studying college student well-being plans to measure several variables. Match each variable to the measurement approach that correctly operationalizes it as a categorical variable.

A researcher collects the following variables from university students: chosen major (Psychology, English, Nursing), score on a 50-item stress inventory, nationality, and psychotherapy status (receiving / not receiving). When preparing the dataset, the researcher recognizes that chosen major, nationality, and psychotherapy status — unlike the stress inventory score — cannot be meaningfully _____ because their values are descriptive category labels assigned to individuals rather than numerical amounts.

A research team is evaluating a published study's decision to operationalize 'psychotherapy status' as a categorical variable (coded as 'receiving psychotherapy' or 'not receiving psychotherapy') rather than measuring it quantitatively. Arrange the evaluative steps in the order that best produces a justified, evidence-based conclusion.

Recall the definition of a categorical variable as presented in the textbook. Identify and list the four specific examples of categorical variables provided in the text.

Explain why the variables collected by the researcher (chosen major, occupation, and psychotherapy status) are classified as categorical variables. In your explanation, contrast how these variables are measured compared to variables that represent a numerical amount.

A researcher is conducting a study on clinical treatment outcomes. They decide to record whether each patient is currently receiving psychotherapy or not. Apply your knowledge of variables to explain how the researcher is operationalizing this psychotherapy status variable, and state whether it is measured as a categorical variable or a numerical amount.
