packed lunch bought lunch

For my analysis, I generated 2 scatterplots and boxplots to visually see where most of the results lied. For the explanatory variable, I set it as either packed or bought lunches, and for the response variable, I set it to weighted GPA. There were 12 more responses for packed lunches, so the results might be a little biased towards packed lunches. I could improve my sampling techniques to hopefully get the same number of each next time. However, judging from the scatterplot, the packed lunch has clusters near 4 while bought lunch has an even distribution from 3-4. The mean for the packed lunches was 3.6 GPA while the mean for bought lunches was 3.3 GPA. The 50% of students who packed lunches had GPA’s above 3.6 while those with bought lunches had GPA’s above 3.3. We can infer that students at Edison High School generally have higher GPA’s if they pack their lunches. There are a lot of lurking variables that are not accounted for such as study habits, classes, and socioeconomic background so the relationship of this study can still be falsely portrayed. Perhaps my next study can find the relationship of these other variables linked with GPA.
