Thanks a lot for taking the time to explain different tests of SPSS! ALL of your videos are so useful! They are proving to be very handy to test my own data for my dissertation 😃

[@Dr.Okolie]

Awesome!! Good to know. Thanks for finding the videos helpful. Best wishes

Dear Dr. Okolie,
You demonstrated that we can remove items from our questionnaires if they result in increasing the reliability. I have a similar case where I might need to follow this procedure but I have some questions:
1. Will we not be criticized in our viva when reporting and explaining this in our study? AND Can it be supported by any source?
2. It's assumed that the values of the removed item are not calculated or included when analyzing the questionnaire?!
I appreciate it and thank you in advance. 🙏 🙏 🙏

How will the different variables or research questions be demarcated on the spreadsheet. Again will the entire sample be used for reliability test

Hello sir. Please can I contact you. U have a serious problem with my spss. I would like your advice.

[@josephbenedictnkache7017]

Thank you for the video, it was very useful. My question is what of if the reliability test is less than 0.3 what do think is the cause and how can it be rectify?

[@Dr.Okolie]

Thanks for watching the tutorial. If the reliability test is less than 0.3, it could mean that your data are not showing evidence of meeting reliability assumptions (i.e., difficult to know whether your questionnaire respondents clearly understood the item statements in the questionnaire).
One way to remedy this is to ensure that you personalize the item statements, and keep the language pretty simple. You can consider recollecting new data using a questionnaire with item statements described above.

Is it acceptable if I report the l cronbach’s alpha of each sub-scale and then also calculate the reliability of the entire scale and report is as total cronbach’s alpha coefficient ? Please answer me I need help

[@Dr.Okolie]

Yes. If a main variable has sub-scales, you need to show the reliability coefficient for each sub-scale and you can also show the entire scale.

How do you know if an item is not doing well?

You can check the the items individually using Cronbach's alpha reliability analysis
