If an educator requests students from various classes in one semester to complete a survey on study skills, which type of survey is this?

This survey is classified as cross-sectional because it involves collecting data from different groups of students at a single point in time, specifically within one semester. In a cross-sectional study, researchers gather information from a variety of subjects at one moment, allowing them to analyze and compare differences or patterns across those groups.

In this scenario, since the educator is obtaining responses from students in various classes simultaneously, it provides a snapshot of their study skills rather than tracking changes over time or through repeated observations. By focusing on multiple classes at the same time, the survey captures a wide range of data from different individuals that can be analyzed for trends or commonalities regarding study skills across the population surveyed.
