Dashboard Week – Day 5

The final day is here. Today's data was about powerlifters, and since we only had half a day to produce our dashboard, little (no) data prep was required. Since we only had to focus on dashboarding, I quickly came up with a lot of ideas which took up my first hour....

Dashboard Week – Day 4

Today was all about Tableau Prep Builder and Web Edit on Tableau Server. We were dealt with pretty harsh limitations for today's data set which was about candy and the sentiment around certain candies. There were 4 different excel files for 4 different years which all...

Dashboard Week – Day 2

The Data School, what do I want out of it?

Now that I have settled in to The Data School, I want to use this blog post as a chance to document what my goals and expectations are at this point. (Hopefully I'll come back to this later and see how it's gone) So what do I want out of The Data School? 1) Expertise...

Catch-DS14

I started at The Data School on the 1st of April, where thankfully I found out that it wasn’t an April Fool’s joke. I was a little bit nervous on Monday, but this was quickly dispelled as everyone here is really nice and super friendly (even Andy). During the first...
