Chi Square Test: Interpretation of (O-E)^2/E

In this video, I try to show how the (O-E)^2/E calculation in a chi-squared test is connected the sum of squared z-scores, something visually closer to the definition of a chi-squared distribution. The video should be understandable to new students of stats and more advanced ones.
