Prof Kelley, you are a savior. I have been trying to understand this concept since yesterday and was on the verge of giving up after 10-12 hours of trying. Was struggling since these are quite new to me. But you have made it so easy to understand and I think I would continue with further analysis on this. Thanks for this..
this is such a great video, I had a lecture about spss and i didnt understand most of it, then I got to this video and you calmly explain everything step by step and it helped me quite a bit. Thank you very much for this video.
When using a software program such as SPSS, the p-value is automatically calculated for you. Alternatively, there are websites where you can provide the Chi-Square value and the degrees of freedom, and they will tell you with the p-value (e.g., do a web search for "p-Value Calculator for a Chi-Square Test").
Do you mean that if all chi-squared tests fail to reject the null, my sampling has a problem? OK i am almost done with the dissertation. Does that mean it is worthless? please help me out!!
Quick question - Assumption 3 states that each category needs to have at least 5 occurrences, yet there are only 4 for No... is this wrong or am I wrong in my interpretation?

Hi prof Kelley thank you for the video! im doing analysis right now. my samplesize is 105. the total population of which i want to analyse about is 6665. my confidence level is 90% and the margin of error 8. Does this change the way i analyse my results from the test?
What is the function of chi square in Excel? I used CHITEST and it gave me the p value. But how to calculate the chi square itself? CHIDIV and CHINV need weird values.
sir I have a problem of stats but I am not getting how to solve problem is two batches of animals each are given test of inoculation , one batch was inoculated and the other was not the numbers of dead and surviving animals are given in the following table for both cases can the inoculation be regarded as effective against the decease at 5℅ level of significance dead. survival. total inoculated. 2. 10. 12 non inoculated. 8. 4. 12 total. 10. 14. 24 can please anyone solve this for me
you said at the end if you get to reject your null then you get to to publish your data. this is find but a major ongoing issue with science is people not publishing when they dont get to reject the null. a negative result can be just as useful be it less interesting for the scientific community.
Thank you for the explanation, with respect but the example here appears to make little sense, as it is obvious to conclude from the observed values that there are more students who work than who don't, why would it be necessary to use Chi-square test in the first place?

I got a basic conceptual understanding of interpreting the P-value in chi-square statistics. I will be you regular follower. Thank you.
You Rock!!! You have a gift of teaching, you make it so easy to understand. Thanks you!
I have been looking and looking to how to write up the results and finally found you! Thanks- I will be watching more!

Thank you sir for this video. I am very grateful as this statistical interpretation for this specific type of nominal data is very rare to find.
Thank you so much for very clear teaching. You are a great teacher.
Thank you. I'm a reading teacher, taking stats ugh!! You are an excellent teacher because I understand it based on your explanations.
Fantastic and compact explanation, thanks a lot for the tutorial!

Thank you for this easy to understand explanation. You must be a good teacher. =)
Thank you soooooooooooooo much for your explanation and the how to write the results.
Hey very useful!!! you are amazing!! I fell in love with your voice!!!
You are Excellent sir thanks a lot for making me understand this
this is very useful for statistics community.Thank you very much sir.
This is Chi Square made easy. Thank you very much
Nice interpretation on Chi Square Analysis. Thank you very much-
All I can say is thank you!
I got well the lesson,hope to play a great role on my finals.Thanks
Thanks so much! I After much confusion, I finally understand it, this is due to your explanation, so thank you :)
Professor you are awesome!

nice............short and easy to understand.........thanks
this was extremely helpful ! thanks !
Thanks for demystifying the chi-square test
Thanks Professor.. Its very useful...
Awesome video. Thanks so much!
Many thanks, you are the best
excellent explanation
thanks alot . its simple and easy to understand :D
Clear explanation. Thanks
awesome, thank u so much
Extremely helpful!
Thank u very much. It enlightened me
Thanksss!!!! It helped me a lot!!
Verry irgent question!!!. Does this mean that there are statistically significant dirfferences between the students?
Great video
Thank you so much..

thanks. it was really helpful
:D
wonderfully explained...thnx..:)
Can you make a video interpretation of a one sample t-test
Thanks

from which book did you get the criteria for chi square ? i need it for reference..thx!

do you have a video for Interpreting the SPSS Output for a odds ratio
Thank you so much..! May Allah give us His guidance...:)
How do you make it neat like that on SPSS?
thanks. very informative.
What is the function of chi square in Excel? I used CHITEST and it gave me the p value. But how to calculate the chi square itself? CHIDIV and CHINV need weird values.
Thank you so much!!
thank you!
sir I have a problem of stats but I am not getting how to solve problem is
two batches of animals each are given test of inoculation , one batch was inoculated and the other was not the numbers of dead and surviving animals are given in the following table for both cases can the inoculation be regarded as effective against the decease at 5℅ level of significance
dead. survival. total
inoculated. 2. 10. 12
non inoculated. 8. 4. 12
total. 10. 14. 24
can please anyone solve this for me
What do I do is I dont meet the expected frequency?
how do u get the value of the chi square
thanks man!
How did he calculate p value? 0.007? I don't understand.
Thank you sir
Which SPSS is this mine output is so different than this
Thank you ...Instigated
we should publish the results even when results are not significant.
you said at the end if you get to reject your null then you get to to publish your data. this is find but a major ongoing issue with science is people not publishing when they dont get to reject the null. a negative result can be just as useful be it less interesting for the scientific community.

The video helped me, but it could have really been explained in 1/3 of the time you took.
cool
You Fail to CLEARLY describe what the null and alternative hypothesis is. You should have a slide for that.
