This is an excellent video- each step is demonstrated in the process of arriving at Cronbachs alpha. This is the first steo in the quantitative/qualitative results for my research. Thank you

Nice video, short but concise and direct to the point! Just what I was looking for for my Thesis. TY.

Thank you for a clear explanation, really easy to understand. I just learned it now for my research survey. Big help!

Thank you for posting this video, extremely helpful! Btw, I wonder if I have more than one section in my questionnaire, do I need to get the Cronbach alpha for each section separately? Hope you can answer this because it helps me in completing my research, thanks again.

@glentox1563

2 жыл бұрын

Hi, thanks for asking. If the sections are measuring different concepts then you will need to do separate Cronbach's alphas. If the sections are measuring the same concepts like disagree/agree and unlikely/likely have similar meanings in relationship to this concept, then you only need to do one Cronbach’s alpha.

Hi! Thank you so much for your presentation. I am doing a research for a post-graduate program, and i am a lost. So sorry for my very basic questions. Do I only use Cronbach’s Alpha after having research participants answered my survey questions (using Likert scale)? Or, can I use Cronbach’s to validate my questions before having participants answer them? Thanks so much in advance for your response.

@glentox1563

Hi, thanks for asking. Before your research participants could even answer your survey questionnaire, it has to undergo validity and reliability test. Cronbach's alpha is a reliability test. Have your survey questionnaire answered by 15-20 initial participants/respondents. (These are different participants/respondents from your research participants.) Gather the data and compute for the alpha.

Thank you sir for the clear explanation, may I know if you have a reference for the interpretation of the alpha level. Thank you in advance sir for any response

Good day sir. I find this very informative as we are currently doing a quantitative research. But, may I ask what's the description of 1-5 from the Likert Scale base on this example? I mean, are 1 and 5 represent 'Strongly Agree' and 'Strongly Disagree', respectively or the opposite? Thanks.

@glentox1563

Thanks for asking. I think the scale here was 5 to 1. Five being the highest positive agreement to the least. However, even if this was reversed, the order does not affect the measurement. Remember that the measurement we are trying to achieve is the correlation of each item in the survey questionnaire.

Hello! First of all, thank you for this amazing video, I was finally able to follow properly :) I have a question and would be very grateful if you could help me. I am currently conducting a test-retest as I have organised 2 pilot sessions for testing the reliability of my self designed survey. However, SPSS does not lay well with me so I was wondering if conducting a cronbach's alpha test would be acceptable? In this case do I conduct a Cronbach's test on my pilot participants for the first session or both?

Hi, thanks for asking. The result should be certified by a statistician or your statistic professor. Sometimes statisticians would also recompute and suggest removing some items to increase the reliability of your survey questionnaire.

Yes, that is correct. The initial respondents needed for the Pilot testing is around 15 - 25 respondents. After the survey questionnaire had passed the reliability test, then it's good for floating to your target respondents.

Hi, thanks for asking. If your alpha is below 0.70, then it has detected some reliability issues that require you to modify the survey or questionnaire. Cronbach's alpha result does not affect the sample size of the study, rather its like a go signal that the survey questionnaire is ready and approved for floating when it passed the reliability test.
