4. Dataset
We used data collected from New Mongol Institute of
Technology.
Description
Final grade GPA of 31 first year students in
2017
Distance Collected using google street map
Family income Taken from questionnaire when
they enrolled
5. Outcome variable
Graded point average GPA.
Independent variables
Distance. measure capturing the distance, in km,
between a student’s permanent residence and her
or his institution.
Family income. Our income measure
distinguishes between students who are low,
medium, or high-income dependent students.
6. Methods
We have only one year of cross sectional data, so
using the LINEAR REGRESSION technique to
evaluate the hypothesis of this paper is the most
appropriate methodology.
The regression equation as:
k=2
7. We want to choose the estimates
of a and b so as to minimize the sum of
squared errors of prediction.
10. We can collect the data into a matrix like this:
y X1 X2
Y 576.0 -22.8 -5.6
X1 151.0 6.8
X2 138.0
Y`=4.06-0.15X1+0.03X2
Therefore, our regression equation is:
Y`=4.06-0.15*distance+0.03*income
