Hey. I love your videos. They're really helping me in prepping for my courses I have in the Fall. Thank you so very much.P.S. Love the hair

[@FlippingPhysics]

Glad to know I can help you prep. Hopefully I can help your students learn in the fall as well!

[@haywanchiu8884]

Great video! could you comment on how you decided to perform 10 trials? Like, why not 3 trials, or 20 trials?

[@FlippingPhysics]

10 is a standard number of trials in a learning physics lab. Enough to show a trend. Not too many to be cumbersome.

Flipping Physics That makes sense, thank you!

Thank u flipping physics.

[@FlippingPhysics]

You're welcome

[@hi_its_jodie]

this is actually perfect

How did you come up with the deviation?

[@nunyabiznasspunk]

was is just sqrt(1/n(Sum i=n(x-xi))^2)?
