thank you

thankssss

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

[@AllieinSK]

This and your other videos were super helpful, thanks!

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

Multumesc mult! Mi-ai fost de mare ajutor

[@immimzi]

Great tutorial, straight to the point!

[@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?

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

[@RawanAdawi]

Thank you so much for the very comprehensive explanation!

[@ayasofya6336]

Thank you for making it easy to understand!

[@anjalimote7010]

It was great help. All doubts are clear.

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

[@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?

[@zoiyaehtisham818]

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

[@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.

[@kossonouprunelle7576]

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

[@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?

[@tx6433]

Great video series, thank you!

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

[@cheikhfalit2462]

Thank you very very much. It was very helpful to me. God bless you.

I LOVE YOU SO MUCHHHH!!!! THANK YOUUU

[@shankhashubhra1049]

Does number of samples effect Alfa score?

[@Rationalreviewer]

Nicely explained. Thank You.

[@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.
