How to Calculate Cronbach's Alpha (Internal Consistency) by Hand
HTML-код
- Опубликовано: 15 июл 2024
- Cronbach's alpha, a measure of internal consistency, tells you how well the items in a scale work together. This is an important way to validate your scale by showing that the items within that scale (i.e., internally) are reliable. In this video, we'll learn how to calculate Cronbach's alpha by hand using sample data.

I think you saved me from failing my psychology final exam. I couldn't understand where all the numbers were coming from or what any values should be before this video, as well as the other video you made before.
Thanks for your explanation, before i did not understand anything about Cronbach's alpha but now it seems easy ! It is very descriptive and detailed, it saved me for my oral exam.
Very descriptive (and nice hand writing skilled) explanation. Cordially thank you!
This was wonderfully helpful. Thank you!
Just recently discovered your channel. Thank you so much for all of the uploads you literally saved me a lot of time in understanding statistics.
Glad to hear! :)
Very useful, a great tool for dissertation. Thanks
M so happy seeing your tutorials because I have found the best psychology teacher....... love from India 🇮🇳
Thanks so much, quite ilustrative.
This guy is amazing!! big fan 🙂
Thank you! This really helped!
That was really helpful! Thank you much!
Thank you so much! It was very helpful.😊
Thank a lot for making it very easy for me to understand

Goat professor
Thank you so very much sir☺️
Heartfelt thanks 🙏🙏🇮🇳
Thank you Dr. Storage! I’m going to crush your midterm on Wednesday!
😃👍
Thanks!
Wonderful explanation and algorithm! Could you provide a literature reference which I can refer to in a paper?
thank you very much > Could you please five me link of software you use it for writing numbers in slides ?
It's called LaTeXiT. Hope this helps!
Will this work if i used different scales for different items??
Like item 1 has response scale from 1 to 5 likert scale while other items have binary response scale yes/no type??
finally!!! I understand it.
francois allwan Glad to hear!
if 18.24 were zero (hypothetically), does that mean we get an alpha of 1.5?
How to calculate the mean of all score?
Sir please suggest me book name for this formula
t h a n k y o u !
Good day may I ask on hiw to get the variance
Absolutely! See this video: ruclips.net/video/y_wdorJ7cXE/видео.html
My question is how to derive that function
SIR PLEASE WHEN I AM TRYING TO CALCULATE MY CRONBACH VALUE IT IS ALWAYS GIVING ME A NEGATIVE FIGURE
I got confused. How did you get the sum of the total column?
The variance of the total column i mena
Hello, excuse me sir, maybe i really need your help today 🤧, because i want to make a reliable results of my research study in my questionnaire and respondents and i dont know to start soving it using the cronbach's alpha 😢....
I hope you notice my comment.
I keep getting 7.278 for the first one
Same!!!
The result shows a high reliability , but the example data looks NOT reliable at all, that is strange
Why are you saying that? Data show internal consistency. Even by observation, we can see that people who chose higher number chose a higher number consistently for all the items and lower for the lower numbers.
@@abhirup780 Thanks， I mean if we compare the data line by line, and suppose that these lines are test results generated by one person repeatedly, then this person's appearance is very inconsistent and unreliable.
