Have you ever woken screaming in the night as you've not fully understood the concepts behind the 5 number summary? Well, this is the video for you as I'm going to spend time explaining this to you and throw in the added bonus of box plots too! I spend time looking at the five number summary which is: minimum, lower quartile, median, upper quartile and maximum values. I look at how these can be expressing using a box plot and how we can show outliers using the idea of fences. So much fun in one video - I hope it doesn't go viral!
