Working Through College
Many undergraduate students are employed at the same time they are enrolled in school. In 2020, the National Center for Education Statistics reported that [latex]40\%[/latex] of full-time students worked.[1] Being employed while in school can help a student pay for tuition, housing, and other expenses, but it can also be associated (either positively or negatively) with a student’s academic performance.
A random sample of [latex]15[/latex] employed full-time students at a large university was selected for a survey on employment. The following is the number of hours (in increasing order) worked per week for each of those [latex]15[/latex] students:
2 5 7 10 16 19 19 22 23 26 27 27 31 40 50
Step 2: Enter a descriptive name for the variable (e.g., Hours Worked per Week).
Step 3: Copy and paste the observations above into the statistical tool.
