Asked By: Zak in Higher Education (University +) - 70 days ago

Wisdom's Answer
This is actually a good question Zak, Universities, schools and colleges usually have something called an intranet which is a faster connection internally they also have a web version to learn from. With this said, when thinking about it ethically education should be wide spread for example if your friends lecturer has not supplied there class with useful enough resources then you give him the information he requires it’s permissible however as you said to publish the resources given to you by the education authority no matter what level it is would need a reference just like when you reference when doing your coursework and assignments they are all Harvard referenced. Credit needs to go back to the original creator its only right.

Wisdom's Answer
This is hard to type, so I'll use "m" for "x bar", and a few other notations that I hope will be clear: Definition: sqrt(SUM[(x - m)^2] / (n-1)) where m = SUM[x] / n Desired formula: sqrt((SUM[x^2] - SUM[x]^2)/n / (n-1)) Now let's do what you started to do, and see if we can manipulate the definition to look like the shortcut: Std Dev = sqrt(SUM[(x - m)^2] / (n-1)) = sqrt(SUM[(x - m)(x - m)] / (n-1)) = sqrt(SUM[x^2 - 2mx + m^2] / (n-1)) = sqrt((SUM[x^2] - SUM[2mx] + SUM[m^2]) / (n-1)) = sqrt((SUM[x^2] - 2m * SUM[x] + n * m^2) / (n-1)) Are you okay so far? The next to last step rearranges the sum. The last factors the constant 2m out of the second sum, and rewrites the third sum, which was the sum of n copies of a constant, m^2, making a total of n * m^2. Now let's use the definition of x bar (my m): = sqrt((SUM[x^2] - 2 SUM[x]/n * SUM[x] + n * (SUM[x]/n)^2) / (n-1)) = sqrt((SUM[x^2] - 2 SUM[x]^2 / n + SUM[x]^2 / n) / (n-1)) = sqrt((SUM[x^2] - SUM[x]^2 / n) / (n-1)) There you have it! If you have any further questions, feel free to write back.
