I would like to introduce you to the wonderful resource of the Kahn Academy. If you’ve been into see you may well have heard me ranting about it but i’m going to rant some more on here anyway!
Salman Kahn started out by making a few algebra videos for his cousins and now has this amazing and free resource (which is always music to ones ears!), of over 2500 videos, practice examples and assessments covering many diciplines from Pure Maths and Physics to Finance, Health Care, Chemistry…you name it!
In each nicely presented 10 minute video he manages to clearly explained each concept. The tutorials are very easy to access straight from the home page. You can even log in to keep track of what tutorials you have watched and gain points and badges for doing so. Below is an example video for you, all about Standard Deviation, something that I get asked about quite a lot!
