Learn how to begin developing a data dictionary.
- [Narrator] Welcome to Section Two of Chapter Two.…In the last movie, you learned what a data dictionary is,…and in this section we will talk about how to set one up.…Some of my students complain that making the data dictionary…is really boring in the beginning, and very picky work.…And it seems like it's a waste of time because…they want to be analyzing data.…If they stick with me and follow along,…they are always happy.…Because like with Dungeons and Dragons,…you really need that map when you are in the…thick of a woods, or even a fence, which is a swampy area.…
You hope you've been keeping up your map…so you know where the swampy part is.…Your whole party can be attacked, and you will not finish…your analysis if you get stuck hopelessly…in a BRFSS swamp.…So be disciplined, and keep up your data dictionary.…In the end, you need a reason for each of the…analytic decisions you make, and you need to be able…to provide that reason if anyone asks.…The data dictionary is part of your data curation documents…that can help you answer those questions later.…
