You became my favorite person in the world. I was really stressed out because a couldn’t calculate the chisq to a result of an investigation, but you explained super clear and finally i can finish my project. Thank you so much!!!
is there a calculator which has the chi-square function but which is non-programmable? because in the exam I am not allowed to have a programmable calculator.
According to you, the Null hypothesis will be accepted if P > 0.05 and rejected when P < 0.05. This is opposite to what this gentleman is stating. Which one is correct? ua-cam.com/video/WXPBoFDqNVk/v-deo.html
Very much appreciated. This helped me cut down 3 hours of hand work down to 30 minutes of excel. You are a life saver. Now if i can just get my group to contribute with our work it will be even less time consuming LOL.
is it association of gender to smoking or the unequal distribution of gender between the groups? Can we say that both groups have unequal sample distribution for each sex? What i mean is can i have test for gender distribution between both groups?
Hi, I was curious why you did not have to use the Chi-Square possibilities table in order to determine if you reject the null hypothesis? Why did you default to alpha 0.05?
.05 is the most common convention and means there is only 1 chance in 20 this result happened by chance. You could choose .01 for a more strict test of 1 in a 100 chance or .10 for 10 out of 100 to be less strict in ruling out the null assumption.
Hi Steve Thanks so much for your video - really useful. However, how do I do the Chi square test for proportions with more than one categorical group. For example, I ask 3 cohorts (healthy, anxious and depressed) if they smoke (yes/no)? Thanks in advance
This is amazing. thank you so much. i had a statistics assignment i was to solve within a couple of hours, but this 8 minute video saved me. keep doing what u do.
Thank you so much for this video. I suck at statistics and Ive got a paper due tomorrow and this has helped me solve a data set in under 2 hours compared to the over 6 hours it took to solve a different data set yesterday :)
Really the best channel in the world many thanks for this brief explanation I am really very satisfied , can you please go with us step by step from downloading R and R studio and show us how to use R we are struggling and the information online is not enough to work on this programme thanks
Thank you so much, i was so stressed and did not find anything helpful until i came across your video. You saved me and my thesis, I can not thank you enough😓❤❤
I want you to know that this video literally saved my day. I have to take a poster to a conference and I kept getting recommended using one-way ANOVA, which gave me very silly results for my binomial data set. Thank you very much friend
If we can accept or reject the null hypothesis based on the chi-square value alone, then why is there a need to derive the P value from it. Why an extra step?
Can I use chi square if I have 4 independent variables to be tested against a Yes or No response? If not, what’s suitable for such analysis? Thanks in advance 🙏
You are truly amazing ... I was tensed due to details mentioned in literature and now uou made it soo simple and easy to implement... wow love your work

A video from 2 years ago SAVED MY LIFE!!!
Thank you for such a great explanation!!!
You became my favorite person in the world. I was really stressed out because a couldn’t calculate the chisq to a result of an investigation, but you explained super clear and finally i can finish my project. Thank you so much!!!
you just got cited in my lab report since I used your methods in my methodology and results section for my results, thank you.
why am i getting 2 different p-values when I use CHISQ.DIST.RT vs CHISQ.TEST
I noticed same. I think CHISQ.TEST works for only 2×2 table
@@ogechichilaka6294I got different results for even 2×2 table
Thank you for this. As someone who hasn’t done stats for 20years this was by far the easiest to follow explanation I have found.
Its very helpful. Thanks. What means if P-value is zero?
It van never be zero, as there is always the smallest probability that it might actually happen
Oh my, this helped me SOOOOO much!!! Thank you!!
thank you i love you you’re a gift of god thank you
THANK YOU SO MUCH! This taught me more than my class lectures lol
You're very welcome!
thanks for the video, it's very clearly explained.
Thank you. Very Good, Simple and Easy to understand
is there a calculator which has the chi-square function but which is non-programmable? because in the exam I am not allowed to have a programmable calculator.
how to do it in r without built-in func?
Thank you so much! So helpful and easier to understand than Coolican. :D
According to you, the Null hypothesis will be accepted if P > 0.05 and rejected when P < 0.05. This is opposite to what this gentleman is stating. Which one is correct? ua-cam.com/video/WXPBoFDqNVk/v-deo.html
Thank You For Explaining Now I know now how to use chi square on my quantitative research
Very much appreciated. This helped me cut down 3 hours of hand work down to 30 minutes of excel. You are a life saver. Now if i can just get my group to contribute with our work it will be even less time consuming LOL.
I have an exam from statistics. You are my savior! Thank you.
is it association of gender to smoking or the unequal distribution of gender between the groups? Can we say that both groups have unequal sample distribution for each sex? What i mean is can i have test for gender distribution between both groups?
The values of p are like 0.7,0.8 , 0.8 , 0.4 etc
Is this a problem . Because i knoe is should be less than 0.05
Thanks for the video. It quite helped in my analysis.
This was superrrr useful thank you so much.
Nice

You are a legend sir
Thank you
THANK YOU so much!!!!!
Thank you, How can we test it for a single variable?
Hi Steve
Thanks so much for your video - really useful. However, how do I do the Chi square test for proportions with more than one categorical group. For example, I ask 3 cohorts (healthy, anxious and depressed) if they smoke (yes/no)? Thanks in advance
amazing explanation, i was not mega sure how it worked :) and ia ma up to date again
Thanks, I liked your tutorial
Thank you! This is so much easier and so much clearer than any of the others!
Sir, I have a doubt. you have done for 2*2variables..Can we do it for 3*3 variables..Is it correct to do chisquare test for 3*3 variables
Thank you so much sir!❤️❤️❤️
Easiest video on chi square. great job.
You are so amazing! The explanation was crystal clear! You’ve literally saved me!! Thank you so much!
Very helpful, thanks
Your video SAVED MY LIFE!!! Thank you so much for such a wonderful & easy explanation
Thank you so much. Can we apply it if the total sample number is 25? Thank you, I really appreciate it.
Thank you so much!!!!!!!!!!! Made it so simple!
Can the interdependence of the categories be established simply by using the Observed values and not using Expected values?
Super helpful for my Botany students when analyzing their experiment data. Thanks!!
Good job for students, thanks very much
This is amazing. thank you so much. i had a statistics assignment i was to solve within a couple of hours, but this 8 minute video saved me. keep doing what u do.

Who else is here from Rosemary Wilsons bum ass class ?
i have a 2-way table with some zeroes in the data set, i cannot find the chi square test in many calculators , can you help? @top tip bio
Thank you so much
Thank you for this. You just saved my life literally😂
THANK YOU VERY MUUUCCCHHHHHHHH
missed my teacher's explanation and this really helped!! ty
is it also applicable when you have, instead of female and male, you have three ages (examples are 18-19,20-21,22-23)?

Excellent. Thank you so much.
Thank you 🙏🏻 for making this video
You're carrying me
Great content
If we can accept or reject the null hypothesis based on the chi-square value alone, then why is there a need to derive the P value from it. Why an extra step?
Actually you can only reject or fail to reject null hypothesis.
It displaying a syntax error message
Thank you so much you saved me for my test
Thank you so much for this, it was extremely helpful!
Can I use chi square if I have 4 independent variables to be tested against a Yes or No response? If not, what’s suitable for such analysis?
Thanks in advance 🙏
can you do one of these with one row and two columns
Thank you so much for this video! So helpful!
Thank you so much, you saved my day
Super tutorial Sir
This video literally saved my life
how do i find my alpha level??
thank you, you save my test
Thank you so much for this! This was great
