I recommend it to everyone in data and analytics-related fields as well as everyone else interested in application of scientific methods. Find the article here: Statistical significance and its part in science downfalls. Enjoy!

Tips for Training Co-Workers in Excel

A friend of mine said yesterday that knowing Excel was everything you need to know these days. It was a joke of course but it had an ounce of truth in it. It made me think again about the role of this application in the office life and even more on the way we acquire the skills.
