​14 Day Data Cleaning Challenge

​Are You Ready For It?

​Data Cleaning Is a Waste of Time!

​Correcting errors and mistakes in your data:

  • ​can be a painful process
  • delays getting your results
  • stops you from doing the most important parts of your job

​If only the data had been collected correctly in the first place...


​And bless him - your boss won't understand.

He thinks that all you need to do is click a few buttons in Excel and it's done.

Even a monkey can do that.




​That's how long it typically takes to clean and prepare a small dataset

​You ​time it with a calendar, not a stopwatch!
