E-Math - Statistics - What is standard deviation 

and how to calculate standard deviation?

I wanted to create my own video to explain standard deviation, but as I was browsing the internet

to look for examples of how others create videos on this topic, I stumbled upon this video. I 

don't think I should reinvent the wheel and I don't think I can explain any clearer than the maker

of this video, so I decided to share his video with all of you.

Click the square bracket at the bottom right of the video to enlarge the video to full screen.

About Unknown

I created this Blog after my students told me that there is very little information about how to solve GCE O Level Math and Additional Math (A-Math) questions on the internet. Even if they manage to find, the solution were for very basic questions. I am a Full-time Math Tutor in Singapore. I tutor mainly in Northern Singapore (Woodlands, Chua Chu Kang, Bukit Panjang, Yishun and Sembawang). I also tutor in Johor Bahru.
