Thanks for easy to understand Cronbach's Alpha video

[@Research_Buddy]

Thank you for your comment Prof.

[@Nsppdians1]

VERY SIMPLE AND EASY TO UNDERSTAND

[@Research_Buddy]

Thank you for your comment !!

[@sisityharar]

thank you😀 You made my day

[@Research_Buddy]

Glad it worked :)

[@sheikhhemo6207]

the easiest way
Thank you Sir!

[@Research_Buddy]

Thank you for your comment !!

THANK YOU SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!!

What if there are 2 different types of questionnaires in a google form, should it be done separately?

[@Research_Buddy]

Yes, if the questionnaires serve different purposes, it is recommended separate testing.
However, if those questionnaires fall under same independent variable, you can do it combinedly.
Hope this helps !!

Hello, out of all these results, which data must I take to present as the individual item's Cronbach alpha?

[@Research_Buddy]

Thank you for mentioning your query. I will try to solve that issue in next video.
However, please allow me to explain you in easier way possible.
In timestamp 01:37 , From Column I to M, Row 1, you can see my first variable "Intrinsic Reward" labelled as 8 and there are 5 column labelled as 8 in the sheet.
It means : for variable 1 (intrinsic reward) I have 5 items. So, if you only calculate Cronbach's alpha for first 5 items, you get individual Cronbach's Alpha.
Similarly, I have 5 5 items each for other variables.
Summary : For each variables, you will have certain items (depending upon how many question you have under each items)
Calculating Cronbach's Alpha of such selected items under each variables gives you your required answer.
Hope it helps !!

what if the validity of the questionnaire garnered an average of 67% only, can it be considered still valid?

[@Research_Buddy]

It depends upon scenarios.
However, we consider above 75% is valid.

[@brooklynbaby2288]

Thank you so much!!!! 🥺🥺 btw which one do i state in my paper if my results:
- cronbach’s alpha= 0.904
- cronbach’s alpha based on standardized items= 0.923

[@Research_Buddy]

Glad it helped you !
Well, I suggest you use overall Cronbach's alpha i.e. 0.904
The standardized ones are something similar to correlation within the variables, not overall.

Thanks...your video help me a lot

[@Research_Buddy]

You are welcome !

[@maheshraul384]

Hello, how can I validate the questionnaire before research

[@Research_Buddy]

@maheshraul384, you need to confirm it with your supervisor/mentor to validate the quality of questionnaire before research.

[@maheshraul384]

Ok thanks

[@fusibact]

thank you 🙏

Great job succinct

Thank you for your comment !!

[@manishaarora7046]

Thank you for this.

[@Research_Buddy]

You're welcome Ma'am !!

[@aurea7508]

Hello, how can I test the reliability of my questionnaire? I have a multiple choice item test. I am ask to test its reliabilty....

[@Research_Buddy]

Please, find the new video for that as below:

[@mjoireb293]

How about pilot testing for multiple responses? Thank you

[@Research_Buddy]

Please, find the new video for that as below:

[@eunpepito3329]

How did you get your mean value in summary item statistics? Thank youuu!

[@Research_Buddy]

At the timestamp 4:38 - 4:41 in the video, you can see I have ticked MEANS as well in the SUMMARIES box.
This is how you will get mean value in summary item statistics.
You can tick more variables if you want like Variances, Co-variances etc. Good Luck

[@nuraimishahirahmohdfadil1734]

Hi , how to adjust mean value if the result is below 3? My mean value is 2.67

[@katy8791]

Hello! Nice video! I wish to know do we need to do pilot testing for exams in a research or is it only for questionnaires?

[@Research_Buddy]

It is only for your thesis or proposal writing.
For physical exams, you'd not be required to do it. Thank you

[@katy8791]

@@Research_Buddy thanks for your response! Maybe there is a misunderstanding... I meant in the thesis, usually we do the pilot study for questionnaires but should we do also the pilot study for student exams ? (Because the exam is an instrument also in the research)

[@cyralvnabor8451]

@@katy8791 the more appropriate instrument to measure the validity of questions in a test is the Table of Specifications (TOS). And yes, pilot testing is also used before you administer your test to your students. Sadly, most teachers don't practice it.

[@mohamedrafeek6460]

Nice

[@Research_Buddy]

Thank you sir !

[@rajeshmandal3784]

That's short and sweet
