59. A student is conducting research on the study habits of fellow students at a college. Which variable of the study is quantitative?
Answer: B
Course load (credit hours) is the quantitative variable in the study.
The course load, measured in credit hours, provides numerical data that can be quantified and analyzed statistically, making it the quantitative variable in the study.
A) Type of residence
The type of residence is a categorical variable as it describes a quality or characteristic (e.g., dormitory, apartment) rather than a measurable quantity. Thus, it does not provide numerical data for analysis.
B) Course load (credit hours)
Course load, quantified by credit hours, is indeed a quantitative variable. It allows for numerical comparisons and statistical analysis, making it essential for understanding the relationship between study habits and academic workload.
C) Major area of study
Major area of study is a categorical variable that classifies students into different groups based on their chosen fields (e.g., biology, history). This variable does not offer numerical data, rendering it non-quantitative.
D) Primary time of day to study
Primary time of day to study is also a categorical variable. It indicates a time period (e.g., morning, afternoon, evening) rather than providing a numerical measure, thus lacking the quantitative aspect required for this study.
Conclusion
The course load (credit hours) is the only option that represents a quantitative variable, as it provides measurable data suitable for analysis. In contrast, all other options are categorical and do not lend themselves to quantitative evaluation, making them inappropriate for the study's focus on numerical analysis of study habits.
