Start Spring Data Cleaning This May!

"It is a truth universally acknowledged, that a single analyst in possession of a good data set … will spend at least 50% of their time in data cleaning and preparation."

Like it or not, data cleaning and preparation are arguably the most important parts of any analysis you do in Tableau. It also is often the most time-consuming part of any analysis. Up to 80% of your time is spent tidying up your data, according to a paper by Hadley Wickham.

But because data cleaning and preparation is about as sexy as an old sock, it often gets skipped over en route to the more-exciting analysis. We think it's about time that we gave data cleaning and preparation some much-needed love. So, with spring (finally) in the air*, our minds have turned to spring cleaning—#SpringDataCleaning, that is!
