Thank you so much, i can found what i need

[@sanjeevantahyog]

How to obtain a desired inter-item correlation value? What if a scale has multiple (say 4) factors? Do I need an average inter-item for entire scale or the average inter item (say 0.3) for individual scale should be acceptable?

[@kossonouprunelle7576]

I have both nominal and ordinal variables in my questionnaire. Can i use this method to check reliability of my instrument?

[@manalahmadsamamahmas2213]

Is alpha test performed on a set sample questionnaires at the piloting stage or at the whole sample at the end of data collection? Thanks

[@muhamadnorasyrafbinsamsudi375]

Thank you so much! It helps me a lot

[@sausan.]

I feel like a loser. They told me to do 1=5,2=4,etc. LOLOLOL. But I have a question. What if you have an Cronbach's alpha of 0.83 and it says if item deleted 0.84. Should you delete the item? Or can you keep the item? I'd love to know!

[@sabhyajuneja]

can i run reliability test having 200 variables and data of 10 respondents?

[@markhan839]

[@athena1169]

Why above 0.7? I mean, where did this come from? Or who initially (history) decides that its more than 0.7?

[@tasnimahmedchowdhury7287]

Very helpful. Thanks!

Sir can you please tell me how to Decrease Reliability from .95 to .70 or .75

[@doquocvietanh]

[@abhimanyu2k21]

Thank you! That's really helpful!

[@godfreyesebamen4729]

This is amazing! Can one use this to evaluate perception of individual to a subject in a questionnaire?

[@bernstmj]

Sorry. I am not sure what you mean. Can you explain further?

[@godfreyesebamen4729]

when hypothesis question says "what is your perception over the subject of discuss" can some one use this tools to evaluate such questionnaire?

[@m.raedallulu4166]

Thanks! It was very helpful!

[@rachellim4272]

many thanks

[@bodynation1]

excellent teaching thx

[@williammutai7093]

why do you feel the need to improve or decrease your alpha? i mean, its your data which you got from the field.. if you get a low alpha it just mean that your work is not reliable, which by the way is not a sin.. it contributes to the existing body of knowledge that the research you did is not worth doing hence cautioning future researchers from adopting your questionnaire and your findings.

[@bernstmj]

So alpha is a measure of whether or not people respond to the items in a similar enough fashion as to aggregate them into a single measure. If I have 4 items and they have a good alpha score, it means they may all be assessing a similar construct and I can average them to create a single value to represent the way people responded. If I have a low alpha score, it simply means people didn't respond to the items in as similar a fashion and therefore, it might be better to treat the items separately. Combining the items anyway, if you have a low alpha score, could mean you're obfuscating what's really going on.
