Do expensive colleges get you the most bang for your buck? Better educators Better results How many classes are taught by professors (with Ph.D.s) instead of professor's assistants? Better classroom life What is the student-to-faculty ratio of the entire school? What is the average starting salary of a graduated student with an undergraduate degree? Sample: We used a stratified method of choosing our sample. We divided our selected colleges up by price range and type of college. Cost to attend each school (for 4 years) Those sections are: High Cost (private university)High Cost (public university)Medium Cost (public university) Low cost (public university)Community CollegeOnline College This graph represents our control variable - all of our conclusions will be drawn by comparing our other data measurements to the costs of attending these colleges.To prove that a higher-cost education yields a better education, the data we collect must correlate directly with this graph. Number of Professors that are Doctors in their Area of Study One of the most important aspects of a school is it's educators, as they are the people that carry out the "education" of a school. So, through that logic, we can determine that, the more qualified, more intelligent, or more well-trained the educators of a school are, the higher the caliber of the school, and the better the education it offers. The following data describes how many of the educators are doctors in their specific areas of study. The areas of study we chose to examine are business, psychology, and biology (they are three of the most popular majors in the United States - USAToday). Percentage of Full-Time Teachers Along with having high-caliber educators, a school must also have present educators as well. Professors that work full-time don't just serve as lecturers - their "office hours" are just as important to a student's success as their classes are. By working full-time, professors are able to schedule more office hours with students and form valuable relationships with them. Therefore, we can determine that if a student has more full-time teachers, they'll get a better education.*Note: the online colleges (Phoenix and DeVry) will not be applied to this data.* Student-to-Faculty Ratio Just as we said above, the professor-student relationship is important in ensuring student success and the delivery of a strong education. These relationships can only be formed if there are smaller classes and a low student-to-faculty ratio. If there are less students per educator at a certain college, those educators will not only be able to talk to the students more often, but also learn about how their students operate, and conform to their needs. Therefore, we can determine that a low student-to-faculty ratio ultimately results in a better education. *Note: the online colleges (Phoenix and DeVry) will not be applied to this data.* Average Starting Salary of Undergraduate Students So far, we've only examined data that evaluates our sample colleges'in-school effectiveness. Here, by taking a look at the average starting salary of undergraduate students, we can determine just how good a college's education is by looking at the results of that education, and not just the method in which that education is delivered. Conclusion Does a higher college education cost correlate with a "better education?" Regression Line Equation: y = (-4.13E-5)x + 21.598 Regression Line Equation: y = (1.357E-6)x + .052 Regression Line Equation (Biology): y = (1.623E-4)x + 4.945 Regression Line Equation: y = .045x + 38440.069 Regression Line Equation (Business): y = (2.37E-4)x + 3.609 Regression Line Equation (Psychology): y = (1.285E-4)x + 10.205 We choose this collection of colleges to be our sample, because they represent the 6 different college types and are each from a different state. Ultimately, through our research, we've found that paying more for college results in receiving a "better education". That conclusion is made clear through the regression lines of every category of data that we analyzed per college: The number of professors that are doctors in their area of study, the percentage of full-time professors, the student-to-faculty ratio, and the average starting salary of undergraduate students after graduating.
