Conclusion

We fail to reject the null hypothesis at the 0.05 level of significance since the p-value is less than α. Thus, there is insufficient evidence to conclude that party affiliation and cumulative GPA for North Olmsted High School students are not independent. One significant point to note is that our study had to be modified – we had to use very broad GPA ranges in order to come up with expected values greater than 5. Despite this, our study confirms what we suspected: Party affiliation does not seem to affect or correlate to cumulative GPA in any significant way.
