Mathematics Homework Help

The Data Analysis Project (DAP), as you know is your opportunity to test one or two hypotheses with variables of your choosing. We are using the General Social Survey (GSS) and the to provide our data and statistics.

THIS PROJECT CONSISTS OF DOING ONE HYPOTHESIS TEST, EITHER A T-TEST OR ANOVA.

One t. is required. You may choose to do a second t. (not the same type) and can earn enrichment credit for that, up to 7 extra points. 

Follow these directions to do the analysis:

1. Be familiar with the GSS data – check out the GSS discussion page for guidance on that. This is, of course, the same data you used for DAP1.
2. To get the test results for the t. you want to do, there are two options.
   • You can use the SPSS program to generate your own t. results! The instructions include videos.
   • You can choose a t. result that I have already generated
     • Look at the files on the DAP SPSS results page so that you know what your options are. 
     • Look at the variable names in the titles of the files and choose tests that use the variables you’ve chosen or those that are interesting to you.
     • Download the file(s) you choose so that you know where and what they are.  
     • If you can, print out those test results and circle or highlight the relevant information that you will need to do the test(s). Use these when you’re writing up your hypothesis test.
3. Open up and write your results in a Word (or other) file, so that you can work on it over a few days.
   • First drafts should never be submitted! Always edit.
   • Always keep back up copies on a few different places (computer, cloud, OneDrive, etc.)
   • You will submit your paper in the pdf format – find out now how your computer does that. Typically, you can ‘Print to’ a pdf file (instead of a printer) or ‘Save As’ a pdf file. Canvas will not accept Word or Google docs or files other than a pdf file.
4. When you are writing your draft:
   • Follow the outline below to write up your t.
   • Follow the five steps of Hypothesis TestingActions and do each t. write-up separately.
   • Make sure you do the full interpretation as needed. Refer to the Hypothesis Testing InterpretationActions sheet and to the individual t. worksheets (and other resources) we have been using over the past few weeks.
5. Remember that your goal in Step 5 below – Interpretation – is to put into everyday words whatever that relationship is (or is not) between our variables.
6. If you choose to do a second hypothesis test for enrichment, it should be the other type of t. – if you use a t-test for the first t., use ANOVA for the second, and vice versa. A second t. of the same type will not be  Please note that this second OPTIONAL t.is #3 on the outline below – skip it if you are not doing it. You’ll notice on the rubric there are no points for it, thus not doing it will not affect your grade – it can only add to your grade if you do it!

Follow this outline to write up your findings:

The sections titled in bold text are required; the section in italics is extra credit enrichment (or for Honors students).

1. Introduction – briefly introduce what you are analyzing – what two sets of variables will you be testing? 
2. Hypothesis Test #1 (use the information provided above)
   1. State your H1 and H0
   2. What is the t statistic?
   3. What is the critical value and what did you use to find it (df, alpha)?
   4. What is your decision about the null hypothesis?
   5. Interpret in everyday words what is going on with your variables?
3. If you do a second t, follow the same format: Hypothesis Test #2 (use a different type of test) You may choose to skip this second t you can do it and earn extra points – it’s OPTIONAL!
   1. State your H1 and H0
   2. What is the t statistic?
   3. What is the critical value and what did you use to find it (df, alpha)?
   4. What is your decision about the null hypothesis?
   5. Interpret in everyday words what is going on with your variables?
4. Conclusions – a  brief summary of what you learned and how it might inform us about people and society.
5. Appendix – attach the pdfs of your hypothesis tests.

There is a rubric for this assignment – please refer to it to see what each section should look like. I will be using this rubric for grading this assignment.
