Explanation
Jenny is studying a specific subset of students (undergraduate sophomores at particular points in time), not every student in existence. This makes her dataset a sample - a manageable subset drawn from a larger population. A population would include ALL undergraduate sophomores across all institutions everywhere. An observation is a single data point, a variable is a measurable characteristic, and a population represents the entire group of interest - none of which best describe what Jenny is collecting.
