Your statistics videos are the best I have ever come across on KZfaq, You are just a genius. Thanks

Sir, I love your videos, and your explanation style. You have single-handedly made statistics much more easier and accessible...!!

Thanks very much, it's a helpful video

Thank you so much for this video . In subsequent videos use examples were the degree of freedom are different . That will make it easier to understand how to read the F table.

I like this man! thank you for the great work

Great teaching...even with a verbal mistake...that can happen...thank you so much for this video..

Sir the video is lit it's great and thumbs up🤝.

Thank you so much for this video! The explanation was clear and you didn't work too fast. You are a lifesaver!

so helpful! thanks!

I wouldn't say the variance is equal, but rather you fail to reject the null hypothesis, or there isn't enough evidence to say they are statistically different.

Very useful 👍

thank you sir

excellent

helpful!

thank you so much. very helpful. IF number of two groups are not similar like df of x group is 11 and df of y group is 13 then how i will use f table. Thank you :)

That does NOT mean the variances are equal!! It only means that the probability of the differences in variance being the result of chance are higher than your maximum allowed probability (alpha). This is a very important difference for actually understanding what exactly you are doing.

Could we rely on the principle that if the calculated F statistic is close to 1, the variances are homogenous?

f.crit in this is actually 2.82 (must have forgot the your glasses here Eugene!)

so in shorttt, you can simply know if its equal or unequal based on the n, its the same so its equal
