I have just seen an article that is too good not to be shared. It is published by Scientific American and discusses issues with the statistical significance and its effect on scientific results. It also lays out the alternative statistical methods that need to be taken into account. It is written in an a readable manner and has lots of links for the curious ones. 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!

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. In my opinion the workplace is where we get the most of it and it is in the best interest of organizations to provide better environment for that. External Excel trainers are good only to an extent as they are usually far from the business context, not that flexible, do not have enough time outside the classes and are expensive. A better alternative is the in-house training by an employee with proven expertise. Another is hiring a trainer that comes from or still is in a business similar to yours to do a customized class. I would like to share with you some tips from my experience for a successful in-house Excel class. It is assumed that the class will be held by a non-professional lecturer.
