A researcher wants to study the relationship between family size and mental health. If the researcher decides to measure 'family size' by recording the number of siblings a person has, and 'mental health' by calculating a score on a depression scale, what specific type of variables are being utilized, and what determines this classification?
Question: A researcher wants to study the relationship between family size and mental health. If the researcher decides to measure 'family size' by recording the number of siblings a person has, and 'mental health' by calculating a score on a depression scale, what specific type of variables are being utilized, and what determines this classification?
Sample answer: The researcher is utilizing quantitative variables. This classification is determined by the fact that both the number of siblings and the score on a depression scale represent measurable quantities that are assessed by assigning a numerical value to each individual.
Key points:
- Correctly identifies the variables used as quantitative variables.
- Explains that the number of siblings and depression scale score represent measurable quantities.
- States that the classification is based on assigning a numerical value to each individual.
Rubric: Award full credit if the student identifies the variables as quantitative and explains that they are classified this way because they represent measurable quantities assessed by assigning numerical values to individuals.

Examples of Quantitative Variables
Which of the following best describes a quantitative variable in psychological research?
In a psychological study, a researcher records the number of siblings each participant has. This is an example of a(n) ________ variable because the data represents a measurable quantity.
In a study on digital behavior, a researcher codes a participant's 'Most Used Social Media App' as 1 for Instagram, 2 for TikTok, and 3 for Snapchat. Because the data is recorded using numerical values, 'Most Used Social Media App' is a quantitative variable.
Psychological researchers use various methods to assign numerical values to their observations. Match each specific measurement approach to the descriptive logic that explains how it functions as a quantitative variable.
A researcher is evaluating different methods to measure persistence in a psychological study. Rank the following measurement strategies from the highest degree of quantitative precision (the most detailed measurable quantity) to the lowest degree of quantitative precision (the least detailed use of numbers).
In psychological research, a quantitative variable is a type of variable that represents a measurable quantity, typically assessed by assigning a numerical value to each individual.
