Chapter 7 A Small Project
This assignment is very much like the previous one, with enhancements.
7.1 What’s the same?
The data: pick from
ACS Census data from California in 2013. (has income, education, race, etc)
What do I do?
- Predict something. Make a claim.
- Do a quick investigation. Display a table or graph. Reflect on what it says.
- Dig deeper: Figure out how that can be enhanced (make it more nuanced; or investigate something related, inspired by the original; or play devil’s advocate, etc.)
- Collect data, analyze it, and make a table or graph that speaks to the issue
- Reflect on what you found out. Possibly, dig even deeper and reflect again.
- Make a shared link to your CODAP document.
- Make it a Google Doc for simplicity.7
- Give your instructor edit permission on the document. They will get an email with the link, so that’s how you can turn it in.
- The report should include a link to the shared CODAP document.
7.2 What’s enhanced?
You may pick your topic
- Advice: mess around with the data before you decide. Make graphs. Think about what they mean. A question or a claim will occur to you. Note:
- If you choose BART data, the BART Data Portal chapter has a section with suggestions for BART topics. That section also has instructions about the “secret meeting game.” Finding the secret meeting is a suitable topic for this investigation.
- If you choose Census/ACS data, you may have already started looking at social-justice topics in a previous assignment, through income differences. That’s a fruitful direction (though not the only one).
- If it makes sense (and it probably will), do a second “dig deeper” cycle.
- Communication is part of data science:
- Make this work stand alone. Do not assume that the reader has read the assignment.
- Similarly, give it narrative sense
- It’s not a numbered list of steps! Make paragraphs! Make them flow!
- The opening paragraph, or some text near it, should motivate the investigation. Why is this interesting—even a little bit?
- Pay attention to space. Usually, if you just paste your graph into the document, it will be bigger than it has to be.
- Make your graphs sing!
- Recoding might be useful: making a new column that’s more what you want
- Briefly describe the data at an appropriate place in the report, including the sample size(s).
- When you present an analysis, explain what you did.
If you used “data moves,” say so! Did you filter?
Did you write a summary formula (like with
sum( )? What was it?.
- Did you drag a column to the left to make groups? Why did you choose that column?
- Do not exceed three pages.
- Vital: somewhere, perhaps in your conclusions, reflect on this experience. What interests you about this? (Or not; be honest!) How is this different from your experience with school math classes?
