  • So standard normal distribution is normal distribution's z-scores distribution?

  • thank you, that helped alot for my exams

  • Thank you so much. My university lecturers aren't great, and I just can't learn maths from a textbook. It helps so much that you have explained it in such a simple, clear way.

  • Im not sure I understood much from this explanation. I would have prefered a more practical application. Could you indicate if you have another video. Also as it relates to the degree of freedom I was a little confused as I thought it was n-1 but you seem to suggest its = to n

  • The semester is pretty much over now... I really wish I'd gotten the idea to go to youtube for help earlier in the semester (definitely would have gotten an A+)!!! Thank you for making these!

  • isn't degree of freedom supposed to be n-1?

  • @ch33v33 yeah, I think it is number of groups minus one (N-1) instead of number of participants minus one (n-1)

  • ur awesome mate

  • I still do not understand how did you get that chart...

  • I'm a bit lost.. is there a preliminary video to this? I don't know the language.

  • My stats teacher just throws a bunch of formulae on the board, and then when you have to do stuff I have no idea where the distributions come from or what they are used for, how to use them, or what they mean.

  • I love this guy.

  • Damn it.. my x's looked like chi's to begin with! 

  • Time stamp 03:00. ONE degree of freedom?!?! Are you sure? Your videos seem to contradict.

  • That is in a normal sampling case. If it is more complex, the degree of freedom is different.

  • brilliant video

  • Thank you for covering statistics!! These statistics videos are so valuable to me, I can finally understand the concepts. Thank you!~ (more on statistics would be great:))

  • Just covered this today. Weird.

  • Could you record a video about degrees of freedom?

  • You're the bessst <3
