Thank you. Clear and detailed explanation in just a few mins. Much better than the rest of other’s tutorial for spss. Especially like your detail, such as internal consistency. Every time I watch these kind of video they just skip these explanations and I have to spend time to find what the words mean, but you saved me from this

Thank you for the explanation. Can i use cronbach alpha also for a questionnaire with different types of questions :likert-scale, binary scale and ordinal scale questions. i would like to know if i should use a different type of analysis. Thank you

[@rufaisabtiwu2075]

Thank you. The video was brief and concise. Does it suggest that a Cronbach Alpa of 0.58 can be seen to show reliability in items if the items are say 30

[@moussabarry7125]

Thank you BrunelASK for sharing this concise and informative lecture. Can you please give the reference of the book which mentioned about the cronbach alpha with at least 0.5 if there are less than 10 items?

Topic 9 - Checking the reliability of a scale

[@robcarlos9037]

Hello, thanks for the video. You explained a few things well but I have a question or 2 if you are able to respond. You say that the 'Corrected Item-Total Correlation has to be > 0.4...our text says 0.50. Now, I have gone through a Factor Analysis and have reduced 30 items to 12 and though on the main scale I have 12 items in which there are 3 subscales, the Cronbach for the whole scale is .82 which is very acceptable however in the 'Corrected Item-Total Correlation' column, about 7 times are below 0.50 but in the Cronbachs Alpha if deleted items, each of these 7 times have lower values than the overall alpha value...With so many times falling just short of the 0.50 on the 'Corrected Item-Total Correlation, what would I do? I don't want to remove more items otherwise I might end up with very few. If yo can reply, thanks...

[@radwanmed54]

Hi Rob Carlos
Please could you help me in explaining how did you get an acceptable alpha value? Because I am running a reliability analysis with 11 items but I got an alpha value of 0.4 which is far below 0.7, the acceptable rate. Please do really need your help. Thanks.

[@omilabubukola8667]

Thanks for the quite explanatory video.
Please, I do have a question: under item-total statistics, subsection "corrected item-total correlation, if item in the scale is a reverse of the construct, can the digit be lesser than 0.40?

[@MahtabAlam-uf8db]

Why do I get a negative value for Cronbach's alpha? I have tried reverse coding, the labels are similar for all items.

[@shankhashubhra1049]

Does number of samples effect Alfa score?

[@estherhering5941]

Hi, I've read the book of Pallant, but I can't find the rule about smaller samples and an acceptable crnobach would be higher than .5? can anyone help me out?

[@zoiyaehtisham818]

why in my Item-Total statistics ,squared multiple corelations are not generated?

[@nikkohayashi5182]

Hello, what happen if my inter-item correlation got - ?

[@bacillusanthracis69]

Can I get the reference for 0.5 alpha value if items lower than 10?

[@aqilafzal_sia4289]

If my dataset statistic output has few mixes of negatively and positively value. Still, my alpha value is more than 0.7, so it is my computation of this reliability test got problems?

[@aqilafzal_sia4289]

Please help me with this to understand why i need to make it either all positive or negative values

[@aisyahputeh4740]

Have you gotten your answer? I have the same problem and wonder about it as well. hope you can help

[@aqilafzal_sia4289]

@@aisyahputeh4740 just let it be. As long as you can determined the end result more or less than 0.7.
