Hi..Thanks for a very video and a good illustration..i just have one query regarding the formula of the statistic t...regarding the denominator term, it is sample standard deviation (s) divided by the square root of the sample size (n)..but some books have used an unbiased estimate of sample variance..and have replaced sample s.d. by that and the formula becomes S (unbiased estimate ) divided by square root of n-1...so which formula is most widely used?? and which one should be used?
Hey- I want to express my gratitude for your excellent explanation of these statistics concepts. I find them very easy to understand. I took graduate stats class. I’m not sure i got those concepts beyond reasonable doubt.
Thanks for using a great teaching tool-great graphs, formulas, examples. I admire your ability to spots and explain the concepts that give hard time.
