Abstract
We decided to find out if an association existed
between car color preferences and gender of high
school students at North Olmsted High School. To
collect our data, we used MINITAB to generate a
random sample of 150 students; we then sent out
a survey to those students asking them for their
gender and preferred color for their car.
Choices for favorite color was silver/white,
black, blue or other.
We got 94 valid surveys back. After gathering
our data, we ran a Chi Square test for
independence. For rows, we put gender, and for
columns, we put car color. Then, we checked the
chi square analysis and expected cell counts to
see if our expected cell counts were at least 5,
and saw that our assumptions were met. We
obtained a p-value of 0.095 at 3 degrees of
freedom. We weren’t able to reject our null
hypothesis at an alpha of 0.05. Therefore, we
couldn’t conclude that gender and car color
preference aren’t independent.
