how to identify Cronbach's alpha of multiple choice questions?

[@TheNursingNotesOfficial]

Follow the same steps dear

[@nikhilbalireddy6208]

are we supposed to change answers? and then again we have to test, just like how you have done in the video?

[@TheNursingNotesOfficial]

exactly Right, its necessary before large scale study.

[@saira_ff]

Is this legal? please reply is soon as possible because i have less time to submit my theses

[@TheNursingNotesOfficial]

It is legal to correct a questionnaire before data collection, and it is also legal when the actual meaning of the modified questions and responses remains the same.
However, it is illegal to modify collected data in a way that changes the actual meaning of the questions and the collected responses.
I hope that answers your question.

@@TheNursingNotesOfficial sir I change same like you change but my data are form 153 respondents is it ok?

[@TheNursingNotesOfficial]

@@saira_ff If you can easily gather more samples, it's generally beneficial to increase your sample size for more accurate results.
The required sample size depends on various factors, such as the study Type, population size, prevelence etc.
You can use online calculators like OpenEpi or Raosoft to determine the optimal sample size for your study.

@@TheNursingNotesOfficial ok sir thank you

[@131BeI]

Cronbach's alpha is not suitable for binary data

[@TheNursingNotesOfficial]

It is an example only to understand how it works. If you are clear, it will help you create Likert scales and other questionnaire types.
