A teacher noticed that the students that she observed studying in the library seemed to be playing with their phones constantly and she theorized that this form of "studying" had to be negatively impacting their exam performance. In order to test this theory, the teacher randomly selects 10 students to participate in a study. The teacher asks each participant to download an application on their phones that they are required to turn on every time they start studying for her final exam and turn off as soon as they stop studying for the exam. The application tracks the percentage of time that each student spends using their phone (texting, accessing websites not related to course materials, making phone calls, etc.) while they are studying. Then, the teacher records these students' final exam scores out of 300 points to see if there is a relationship between phone distractions and exam scores (see data below).
Student # | % of Time Spent on Phone While Studying | Final Exam Scores |
1 | 7 | 296 |
2 | 28 | 278 |
3 | 64 | 207 |
4 | 15 | 211 |
5 | 22 | 275 |
6 | 3 | 281 |
7 | 39 | 242 |
8 | 46 | 229 |
9 | 12 | 294 |
10 | 51 | 188 |
