Purpose: The goal of our survery is to examine the dietary habits and preferred dining locations of Georgia College students, to determine the correlation of eating lunch on/off campus vs. cooking for yourself between omnivores and vegans/vegetarians.
Methods: We randomly asked 45 students from popular locations in and around Georgia College's campus, including the library, Wellness Center, and Blackbird Coffee in Downtown Milledgeville. The students were of all ages, genders, and majors. This technique is called random sampling, where anyone in the GC's population had an equal chance of being selected.
Survey: We asked 3 quantitative questions:
1. How often do you eat lunch on campus weekly?
2. How often do you eat lunch off campus weekly?
3. How often do you cook for youself?
Results: In our presentation, we included bar graphs including each set of data for eating on campus, off campus and cooking for yourself. The bar graph illustrates all of the sampling data. The bar graphs show that the vegans and vegetarians were more likely to cook for themselves rather than dining on or off campus.
In the first scatterplot we compared the number of times cooking for yourself and the number of times eating on campus weekly. It seems from the line of best fit that there is a strong negative correlation with relatively few outliers. This means that the more people that cook for theirselves tend to eat on campus much less.
In the second scatterplot we compared the number of times cooking for yourself and eating off campus. This graph illustrates a slight negative correlation, but the data is spread out having many outliers.
The third scatterplot compares the number of people who eat off campus and the number of people who eat on campus. Like the second scatterplot, this scatterplot shows a slight negative correlation with many outliers as well, meaning that peole who eat off campus are less likely to eat on campus.
The two pie charts we created include the number of times an omnivore cooked for themselves and the number of times a vegan or vegetarian cooked for themeselves. The results show that the omnivores were less likely to cook for themselves and the vegans and vegetarians were more likely to cook for theirselves. This shows that someone with a more healthy diet, not necessarily vegan or vegetarian, tends to cook for themselves.
According to our summary statistics chart, we can conclude that on average students eat on campus 3 times, students eat off campus 2 times, and students cook for themselves 2 times. The standard deviation of eating on campus and cooking for yourself was roughlt 2, meaning that there was that much variation from the mean of the data set. The standard devaition for eating off campus was roughly 1 meaning that the data points were more closely associated with the mean.
Our contigency table displays the two categorical data and the number of times students cooked for themselves. The results from the contigency table show that the vegans and vegetarians tend to cook for themselves more often, but some omnivores cooked for themselves more often as well. A larger sample size would have displayed more accurate results between the two types of data.
In conclusion of our data and graphs, we found a slighty negative correlation from being an omnivore or vegan/vegetarian and their dining habits. We conclude that the more someone cooks for themselves, even if they are not vegan or vegetarian, they tend to not dine out as much. A larger sample size could have altered our results, especially if we were able to find more vegans and vegetarians.
