what do you do if you have a chisquare value less than 0.05

This was such a helpful video. Thank you so much!

What would one have to do if I have two correlation coefficients taken from the exact same sample (repeated measures). For example, I want to compare the relationship between sleep quality and optimism for two moments of measuring, thus having an r correlation for measure 1 and then giving the same subjects the exact same questionnaires at measure 2 and obtaining a second r correlation. Now I want to compare those two r's. How do I do that? Because I have dependent samples and only 2 variables. I have almost searched the whole internet and feel totally stuck... Could you maybe help me?

You are the best ever tutor. I have been for two hours reading and watching videoes, none of what I read or watched was as good and straigtforward as your video. Hats off

Where do I find appendix A?

what package did you use?

These videos accompanying your book are an absolute treasure for me. Many thanks for this amazing piece of work!

Thanks Sir!! Your channel is very helpful. May God shower his blessing upon you.

why the screen is blurry?

For anyone watching, If you dont remember the idea in the video that you're supposed to find the percentage value as a decimal (meaning divided by 100 into your calculator) on the value appendix, you'll be stuck looking for an exact value which they dont always have that corresponds to a z score, dont forget that step because then you'll keep wondering why you get it wrong.

Would never have seen that formula if it wasnt for this video. My prof uses a long and variable dense formula that does not help

Thanks. But how can draw diagram from it??

Thanks for the vedio. It was useful. I was wondering if you can confirm whether the procedure you are using in this vedio to test the difference of coefficients of correlation for Pearson r is valid for correlation coefficients obtained from Spesrman rho as well???

It was very helpful thank you 😊

Hello, how we can do extract items or load on different factors? For example item "approach1" loads on both Factor1 and Factor3.

Can you visualise how to derive SE from the sample sd?

Hey this helped me a ton! Would you want to follow up the main effects with any post-hoc tests? I'm asking because I ran a three-way mixed ANOVA and need to interpret the main effects. Thanks!

newborns need to get it together

Great one there but the codes are not very clear for sight

Thank you for this!

This was filmed on a TI-84 Thanks for the help

Tq sir

Can Cronbach's alpha be calculated on a single item? Or that does not make sense?

Old video but THANK YOU! My school did not explain this besides formulas but my homework questions were on this subject.

now i get it hats of to you sir ...!

Thank you for this explanation! Very useful for my PhD project!!

This video was very helpful, thank you.

How would you know the population standard deviation, if you don't know the population?????

Thank you so much sir for your amazing book which is so, so very helpful in understanding Statistics easily. And thank you for all these video and other resources too.

Great...👏

Thank you!!

lifesaver, thanks!!

incoherent explaination

Thankyou so much for explaining this

Thank you so much for this!

THANK YOU SO MUCH!!!!!

Thank you this really helped

Waaay shorter and more effective than the video that first came up from Khan academy for my question. Thank you so much!!

Thanks for the explanation. However, at the start of the video, you show the formula for std deviation as [Σ(X - X^2)^2]/(n-1), and not t [Σ(X - Xbar)^2]/( n-1) . Kindly explain.

Thanks

Thank you so much for this short and sweet video. VERY helpful indeed,

Hi sir, I am not a statistic student, i m Sociologist but there in my book a question is given, please solve and send me, i will be thankful to you. my Email: shayansps@gmail.com QUESTION . The grades in various subjects of a student are given below. Test at 5% level of significance that there is a significant difference in grades Mathematics 72 80 83 75 Statistics 81 74 77 88 English 82 90 87 80 Research 74 71 77 70

Thank you ♥️

Sir, please help me in solving this... for the following data, calculate the standard error for mean when the sample is drawn under without replacement scheme. number of motor cycle accidents is 4.1 in a random examination of 8 cases out of 2500 with standard deviation being 0.9

Thank you, sir! Clear explanation and very helpful!

So it’s SEM the same as SE?

thanks Tony Montana

Thank you this was very helpful
