Thank you for this video. Btw I have a question concerning degrees of freedom. Shouldn't we substract 3 to the number of cells? Because we estimated 2 parameters : the mean and the standard deviation.
Nope, range/sqrt (n) makes more sense. One more thing to add: at school I learnt to calculate the number of classes by taking the square root of n ( the answer then is 11 i.o 8) someone then does it wrong.

i think you are right, df should be 120-3=117
@@vickywu1314 For a chi squared test DF = #bins - 1 -2 so the DF should be 5 not 117 I believe.
You're an absolute ledge mate. Cheers!
very nice
Awesome video, spent forever trying to figure this out!
Sir what is that thing 1+3.322(log).in finding cell value. Is it common for any dataset. Please answer me. Urgent
Is it common?
