SPSS Analysis

There are many factors that influence student success in college. This project will use
fictious data to explore the impact of many key factors and characteristics on college success using
a range of statistical methods within SASS. Most of the analyses will focus on the ACT test, a
standardized test used in the college admissions process.
Part 1: T-Test
1. T-Test for a single sample
Most college freshmen enter university directly after finishing high school. This first
hypothesis test will validate this by conducting a t-test for a single sample on participant age. The
null hypothesis is that the mean age is 18 while the alternative hypothesis states that the mean age
is actually higher than 18:
H0: µ = 18
Ha: µ > 18
A t-test will be used because the population standard deviation for age at this specific
fictious college is unknown. First, the distribution will be checked for normalcy using a Q-Q plot:
As most of the data is close to the line, except for a few outliers in the mid-20s, the data is normal
enough to apply a t-test. It is important to note that age is measured in whole years, so overlapping
data points are not visualized.
Results from the t-test are:
