Project DOs and DON'Ts
- DO submit your project on paper.
- DO put your name, the class meeting time and the current date on your project.
DO show all the information that is displayed in the sample project.
- DO follow the rules of graphing stated
during the semester.
In particular, if your data has units, provide the units in the axis label.
- DO use a word processing program like Microsoft Word to create your semester project.
- DO present your project data in a
single table. Unless you have more
than 32 subjects, this table should fit on one side of an 8 1/2"
by 11" sheet of paper.
DO present the sources of all your data giving titles, locations, publication dates, and dates you obtained the data from the internet.
- DO check if necessary to make sure you used the correct variables for the qualitative bar chart, the side-by-side box plots, the dependent difference test, and the scatter diagram.
- DO organize your project presentation. Analyses of graphs should be near the graphs.
- DO answer the analysis questions for
histograms, box plots and scatter plots with complete sentences. Your answers should have all the
information contained in the questions, so you won’t need to rewrite the
questions. The analysis for any one of these graphs should be written as a paragraph.
- DO make sure your written descriptions
and analyses are clear and make sense to someone who has not taken statistics
or has forgotten their statistics course work.
- DO include test statistics and either p-values or critical values for the chi-square goodness of fit tests, the Ryan-Joiner tests for normality, the dependent difference test, and the test for significant linear correlation.
- DON'T use covers, folders,
notebooks or page covers for your project. If a standard staple won’t hold your project together, you are
doing something very wrong.
- DON'T use data from ESA 1 or the
sample project data or the sample projects contained in this website.
- DON'T copy the wording of the
sample project verbatim. You should
be working with different data from a different situation, so the wording of
the sample project will most likely not apply in your situation.
- DON'T show me your
calculations. I just want to see
your results. If your results look
unreasonable, I will check the calculations myself.
- DON'T number your answers to the
histogram analysis or boxplot questions.
- DON'T use 3D histograms or 3D bar charts. The 3D style of charts are more difficult to interpret.
- DON'T make your histograms with less than 4 classes or more than 6 classes.
- DON'T tell me you have a P-value of 0 or a P-value of 1. If your calculator or computer software gives the P-value as 0, then say the P-value is less than 0.001. If your calculator or computer software gives the P-value as 1, then say the P-value is more than 0.999.
- DON'T tell me you have a P-value bigger than 1. If the P-value came from your calculator, there is an E followed by a negative number at the right end of the number you read. This means the number you wrote should be multiplied by 10 to the corresponding negative power.
- DON'T use "Data" or "Index" as axes labels. These are default labels that Minitab uses, and they should be changed to a label that provides more information about the data being graphed including the units, if the data has units.
