In this video, you will learn how to get mode mark, mean, median, variances and standard deviation from a group data in SPM Add Maths for both paper 1 and paper 2. This video is very important especially when you forget how to use the formula for median and standard deviation. Anyways, If you would like to have more interaction with me, or ask me more question, or suggest some chapter u want to learn, please add the facebook page at "y=mx+c" or www.facebook.com/maths.video.
