Statistics Project
50 points
The objective of this project is to incorporate the various topics of this
course into a comprehensive report. Graphs, summary statistics, regression
models, confidence intervals, and hypothesis tests work together to give
quantitative support for theories.
In your role as researcher, you are to propose a research hypothesis and collect
data to determine if your theory is valid. (Quantitative data is recommended since it is
the focus of this course.) There are no restrictions on your topic, but you must apply the
techniques learned in class to support your conclusions. You may collect your own data
through observation, experiment, or survey, or you may use data from other sources such
as almanacs or the internet. The data must be included with the project, either displayed
by Minitab, or attached as an appendix. If you use a survey, attach a copy.
The report must be typed and placed in a folder. It must include appropriate
graphs, summary statistics, at least one confidence interval, and at least one hypothesis
test. Minitab must be used unless an exception is granted. No length is specified, but it
will be graded according to the percentages given below as to how well it accomplishes
the following:
10% Abstract
10% Clearly stating the purpose of the research
10% Describing the sample and any possible bias
20% Producing appropriate graphs (at least 2)
10% Producing appropriate summary statistics
(mean, standard deviation, etc.)
25% Constructing a confidence interval and performing a
hypothesis test
15% Giving relevant interpretations and conclusions
Suggestions:
1. Repeat a study that was reported in the media. For example, examine how
many hours are spent each week watching TV, or compare the mean number
of automobile accidents of men and women.
2. Select two variables that seem to be related and perform a regression analysis.
3. Validate or refute the “Freshman 15” rule.
4. Determine if a baseball team’s ERA is related to its winning percentage.
5. Determine the mean number of kernels that don’t pop in a package of
microwave popcorn.
