Thank you!!!! I've been stressing myself trying to find software to do this, when all I needed was someone to explain to me how to make use of my variance data.
This has helped me with my ABA work (I'm creating a TPB questionnaire on engaging in life skills for adults with mild IDD as part of a current skills assessment using the COM-Bmodel) and I found this so palatable and easy to understand 🎉
Thank you so much for this video! I have been overwhelmed trying to understand how to calculate reliability for my grad school research results, and this helped my non-statistical brain so much!
Currently working on my Thesis which focuses on the SDGs (Sustainable Developmental Goals) and I did some of the interpretation, just got to have it checked with my professor to see if I did it correctly. Will edit for any updates.
I noticed that in the formula that the variances and sum of variance are squared but you didn't square them when you wrote the equation. Was that on purpose or is it an error?
Hi Jan, No - it is not necessary. But be careful how you calculate the variances - you will be using values in lines rather than columns. Hope this helps, Dr E.
I'm just asking (I'm not sure): Shouldn't you be using the function var.P instead of var. S since you are dealing with the variance of the total population?
Hi Steven, Normally we use samples (in the video the sample size in 20), and therefore do not know the population statistics such as population variance (var.p). Sample variance (var.s) is a good indicator of population variance, therefore it is usually OK to use it instead. Hope this helps, Dr E.
this video is easily understood and precise, I can’t thank you enough Professor- may your life be filled with glee and blessings all the way!
Clear, concise and straight to the point. Thank you very much Prof. Eugene.

this might help enough my study for the test of reliability, its so easy to understand. thank you Professor Eugene!
Finally, someone who explained why the Crombach's Alpha is necessary in a clear way!!! Thank you!

Very very clear presentation, The flow of the explanation is smooth and very easy to understand. Thank you very much!!!
Thank you, Professor. This was certainly helpful and easy to follow.
Thank you so much for the most easiest way to calculate the Alpha. God bless you!
This video is an illustration of the word "concise". Well done.
very clear and understood. thank you very much prof. Eugene.
Your video is helping me finish my thesis! Thank you so much
you are getting me through my psych stats math! Thank goodness for you
This is explained really well, thank you for making it so clear and using an example to show this.
You're very welcome!
Thank you very much Professor Eugene!
thank you Eugene .. god bless you .. you saved my day
This totally helped. Thank you!
Thanks Prof. Up until now i thought to get these value, spss was the only way...
Thank you so much for this video! I have been overwhelmed trying to understand how to calculate reliability for my grad school research results, and this helped my non-statistical brain so much!
You are so welcome!
Thank you so much for such a clear and easy to follow video!
Glad it was helpful!
What an explanation! Thanks a lot!
Thank you so much Prof🙏. Very informative for all beginners .....
so clear, thanks a lot for the explanation - never been so easy!
Glad it helped!
Fantastic Video, it helped me so much, thank you!
Thank you very much for this simple and concise tutorial, you really saved me for my uni project 😤😤😤
Glad it helped!
Great lesson.
Thanks!

Best explanation!
hello Prof Eugene, it's very helpful. Do you still have other videos of the computation of reliability?
very useful thank you
Thank you so much sir!
VERY WELL EXPLAINED
Cheers man! Saved me having to learn SPSS. I realise now SPSS is just a poor man's excel. Helped out a final year dissertation student :D
Glad it helped!
thank you
mr legend
Thank you, sir!
I do have a question, do you use your actual survey questionnaire to the sample that you are going to be using in determining the reliability?
thank you so mauch
Explained very well. Thanks!
Thanku so much sir ❤🙏
thanks so much!
Thank you, thank you, thank you.... 1000x thank you!
Welcome!
I've implemented the formula as explained in this video on my sample but cronbach's alpha value is coming to be negative. What do I do?
Mera bhi
Thank you
How to calculate if two observers did piloting for same subjects on different days?
I noticed that in the formula that the variances and sum of variance are squared but you didn't square them when you wrote the equation. Was that on purpose or is it an error?
What is your formula to get the variance of the total column?
Thank you!
Welcome!
I am getting #NAME? while I apply variance function?
thanks
Need help 🥺 what's the possible reason why I got a negative answer
You didn’t use the squared was that an oversight or it is not needed?
how will i know which item should be removed because of inconsistency?
Hi! Is it necessary that the question number is in the x-axis and the respondents is in the y-axis?
Hi Jan,
No - it is not necessary.
But be careful how you calculate the variances - you will be using values in lines rather than columns.
Hope this helps,

I'm just asking (I'm not sure): Shouldn't you be using the function var.P instead of var. S since you are dealing with the variance of the total population?
Hi Dr Alonso,
In my example here I am using a sample of 20 in a pilot study, so sample variance (var.s) is most suitable.
Hope this helps,
Dr E.
Thanks, I understand now, you are working with a sample. Thanks again. Good video.
Sir, why did you use Var. S instead of Var. P?
Hi Steven,
Normally we use samples (in the video the sample size in 20), and therefore do not know the population statistics such as population variance (var.p). Sample variance (var.s) is a good indicator of population variance, therefore it is usually OK to use it instead.
Hope this helps,
Dr E.
How did you get the total 6.67?
Hi Christian,
This is shown at about 3:25 in the video. It is the variance of the total values.
Dr E.
Can not hear it well with all volume up
