Glad it helped you !!

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.

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 !!

You are must Welcome. Glad I could help you !!

Glad it worked :)

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

Ok thanks

Thank you sir !

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

@@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)

@@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.

The analysis software is SPSS and the raw data collection is Excel.

You are welcome !

You're welcome Ma'am !!

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 !!

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

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

Thank you for your comment Prof.

Thank you for your comment !

Please, feel free to ask in the comment if you have any confusions.

Thank you for your comment !!

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