Final Research Report

Lime cat sez use your brain. 


What do you need to create for the final research report?   The description of the assignment is  here:
Read these instructions:
https://docs.google.com/document/d/1kQQHDh6uhIuaoWl_LWCDaAYobMGSRriBFiFUT8YYQG8/edit
USE THIS DATA: http://db.tt/JjeomqVk

Create your document and share it with Ted Now:

See newly added examples on using excel here:

But here are the instructions in a nutshell:
  1. Use the data we collected to describe patterns in the variables we collected. 
    1. use your brain to find interesting things to look at
    2. Here is the link to the final data set.   please download it and save a version of your own on your computer, or to your USB drive, or to Dropbox-- wherever you prefer to store your important files: USE THIS DATA: http://db.tt/JjeomqVk
  2. look for patterns in how some variables are related to others. 
    1. Use your brain to come up with interesting variables
    2. Display the results in interesting ways
  3. Then right up what you found in a summary with the same general format as the abstract assignment. 
    1. The details of what to include are in the link above
  4. The dataset is NOW ready.  
    1. The first step is to create some basic descriptive statistics, and create some new variables that might be interesting. 
    2. Next step would be to make some graphs that would be potentially informative.
  5. This is an exploratory study--  you need to do some exploring.  Not all of your explorations will end up being noteworthy.  
    1. I will start adding examples of things you can create in excel.   I will start with how to make transformed versions of your variables.
  6. The phrase "use your brain"  is a joking way to emphasize that there are many hard parts of doing research-- but one of the most difficult is figuring out how to learn something interesting from the data. This takes effort, and is hard to teach, but is demonstrated in the research that we read for HW2.

  1. some comments from the google doc on using excel:

    Anonymous User 2: Hey Dr. Welser, do we need to do the logs of the data in the Lonin Data and histograms for our final paper??
    This part really confuses me and im not sure what i would use it for in my paper

    me: check out the very last plot on this document
    it is not required or anything-- but you should think about why I did the log transformation given how the variables are actually distributed.

    Anonymous User 2: ok but would i have to do the logrithim and histogram to get that?

    me: no-- the important thing is to think about what you want to look at in the data and try to do a good job of whatever you chose to do.
    It might be helpful to look at the textbook and see how it describes descriptive statistics and plots and what they are good for
