Step 1: Choose your topic
• Choose a topic where there are theories, research and studies already available so that these would serve as your reference and starting point.
– In the research tradition, these existing theories/research/studies from EXPERTS will provide “grounding” or foundation for your paper.
– It’s not why YOU say, it’s what EXPERTS say/found.
Step 2: Have you researched/reviewed existing studies on your topic and used these studies to pick your X variables (at least 3 required)?
• Your topic (your Y variable) must be expressed in numbers and that these numbers must be different.
• General format fits the question of “why is there variation in the Y variable?” or “why is it that the Y variable is high/large for some and low/small for others?“
– For example, if Y=GPA of college students in each U.S. state, then the question becomes “Why do students in some U.S. states have higher GPAs than students in other states?”
• To answer the above question, you must have a
minimum of 3 explanations/reasons (these are
your X variables).
– Although some X variables are obvious (for example,
X1=number of hours students study per week, with the expectation that students who study more get higher GPAs), be sure to use theories/existing studies to choose the X variables. These theories/studies will also tell you if you have more than 3 X variables.
• Make sure that your Y and X variables can all be
expressed in numerical values.
– This is the only way that Excel can run your regression model.
• Make sure you know where (which reliable websites) you will get the numerical values of your Y and X variables.
Research Question: Why do some students have higher GPAs than others?
• Y = GPA on a 4.0 scale
• X1=numbers of study hours per week, which is an actual number
• X2=course load, measured by the number of course credits currently taking or an average course load per semester
• X3=number of hours a student works per week, which is an actual number
Note that I chose X1, X2, X3 because of studies/theories that say each of them affect a student’s GPA, not because I think they should be my X variables.
Step 3: Have you constructed your initial regression equation and specified your Y and X variables?
General Equation: Y = a + b1 X1 + b2 X2 + b3 X3
Specific Equation: GPA = a + b1 Study Hours + b2 Course Load + b3 Work Hours
Hypotheses (based on theories/studies/research):
• The more hours students study (higher value of X1), the higher their GPA (higher value of Y)expect b1>0
• The more credits students take (higher value of X2), the more pressure on their grades, the lower their GPA (lower value of Y)expect b2<0 • The more hours students work (higher value of X3), the less time/energy they have to study, the lower their GPA (lower value of Y)expect b3<0 Step 4: Have you decided how you will measure (in numbers) your Y and X variables? Y= GPA (out of 4.0) X1= study time in hours per week (average) X2= number of course credits per semester (average) X3= work hours per week (average) Step 5. Have you decided where you will get the data for your Y and X variables?
