I made this notebook to try and calculate the volatility of the AAPL stock on 03-20. Does this look right?

The above isn't exactly correct. Volatility typically refers to the standard deviation of returns and not of price. More accurately it is the standard deviation of the 'log returns' but they are pretty close. See https://en.wikipedia.org/wiki/Volatility_(finance).
I added some cells to the notebook to show the calculation. Good luck.
