Taking a college 3-week Statistics Course and your video helped me earn a 90% on today's exam. Thank you!!

This is so genius! Thanks for making it easy to comprehend all the different types of t-tests, including the usage of the f-test to check variance.

And I like the way you summarise everything at the end, to see the data output by excel and decide if we can accept or reject the null hypothesis.

Thanks a lot man! Keep it up!

Thanks for the video..

I don’t get it all how do you make the conclusion for the f test … to test equality of variances?

Thanks

[Ivyana]

This was very helpful! Just one question, why are you using a one-tail T-test and not a two-tail T test?

[joan]

Hi, if my alpha = 0.05 and my P(F<=f) one-tail = 0.05637794, whether there is a significant difference exist between the two population variances?
