Exercise Sample Variance
I tried the exercise on this lesson, and got the right answer, BUT I still don't know what it means, here is the explanation from the exercise solution:
Variance: 133,433,409,536.36
Explanation: There is great dispersion between the income of different people in the USA(sounds like a slight shot at the income disparity lol, sad but true!)
My question is, what does the number mean when compared to the mean of $189,848.18? What am I missing that it's not connecting for me?
