Editing Statistics and Statistical Programming (Winter 2021)/Problem set 7 (section)

=== PC2. Import, explore, clean ===

As I mentioned above, the full WA-SOPP dataset is over 11 million rows, so I have created a random 1% subset for us to work with in this assignment which is [https://www.dropbox.com/home/COM520-shared_files-UW-2021-Q1/datasets/problem_set_7?preview=wa_statewide_2020_04_01-com520_1pct_sample.csv our Dropbox here repository here]. It's about 28MB.

To get started, you'll want to import the data and explore its structure as well as key variables that we'll be focusing on in this analysis (<code>date</code>, <code>subject_age</code>, <code>subject_race</code>, <code>subject_sex</code>, and  <code>search_conducted</code>). Inspect a random sample of rows to get a sense of the data. What (if anything) is missing? You may also want to clean/recode some of the key variables. Make sure to explain and justify any data cleanup and/or recoding steps you decide to take.
