Our Purpose: With the demands of school work in classes, rising tuition, and many of the other expenses college students face, we decided to see if : For SLCC students, is the number of hours worked in a week related to the number of credit hours taken during the semester?
Using a systematic sampling method of every fourth person, SLCC students will be surveyed about how many hours they work per week, and how many credit hours they’re taking. Sample Size: 125 SLCC Students - 5 group members each survey 25 individuals Survey with two questions: - How many hours do you work per week? - How many credits are you taking? Our Plan:

Scatter Plot with Line of Regression
Fairly minimal Deciding a research topic. formulating a research plan with appropriate variables. difficult for our group to get together and coordinating through . Everyone had a busy summer and a couple lived far away. Creating Boxplots in excel! Difficulties and Suprises
The distribution was created a frequency plot out of the hours worked in one week by our sample population. The histogram and boxplot created from our first variable are skewed to the right. ^This means that our median lies in the left of our data plot and there lies towards the right a few variables with higher values. We have one outlier at 56 hours worked in one week. Out of our sample we found that students tend to work between 15 and 25 hours a week. The scatter plot shows there is zero correlation between the data. Our Our data has a weak linear correlation coefficient. This proves no correlation between the two data sets. Coefficient= Analysis
By observing the data (calculations, graphs and plots) it was found that there is not a correlation between the two sets of data collected. We found that r(125)= 0.12, p > 0.05 which shows that the correlation coefficient was less than the critical value of the data. Thus proving that there is no way we can be 95% confident that there is a relationship between the two sets of data. In order for us to be confident there is a relationship between the sets of data there would have needed to be a positive relation in students taking more or less credits at SLCC based on how many hours they are currently working, which there was not. Interpretation
Our research question “For SLCC students is the number of hours worked in a week related to the number of credit hours taken?” was answered. The predictor variable in this question was number of hours worked and the response variable was number of credit hours taken. We found that there is not a relationship between the two variables. You can tell this by seeing how scattered our data was. This shows that there are other reasons for explaining how many credit hours SLCC students take. Conclusion
