Think about what could be improved about this data. In a text file (to be turned in as part of the assignment):

1-5. Describe five things about this data that are not tidy and how you could fix each of those issues.

6. Could this data easily be imported into a database in its current form?

7. Do you think it’s a good idea to enter the data like this and clean it up later, or to have a good data structure for analysis by the time data is being entered? Why?
