A study was conducted among a group of 100 college students to understand their weekly

study habits. Each student was asked how many hours they dedicated to studying and

coursework outside of class over the past week. The dataset represents the number of study

hours reported by each student.

This information is valuable for gaining insights into students' study patterns,

understanding the average amount of time students devote to self-study, and identifying

any trends in the distribution of study hours. The data can help us explore if most students

are following recommended study hours or if there are significant variations across the

group. This could further assist in academic support planning, enabling the college to

encourage effective study habits:

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
