Cronbach's alpha (or tau-equivalent reliability) is a measure of the relationship between a group of questions. The group of questions is called a scale and each question in that group is an item. Cronbach's alpha is therefore a measure of the internal consistency of a scale and thus of the strength of its reliability.

Hi there, when you say "the goal now is that the responses to the various items match well, i.e., are highly correlated", does it matter if some questions are highly positively correlated while other questions are highly negatively correlated? How does the sign of the correlation affect Cronbach's alpha?
@brendansharp4856
@brendansharp4856 Год назад
Im pretty sure it doesnt matter if they are positively or negatively correlated. The aim is to measure consistency, so whether that is positive or negative doesn't matter but rather that consistency does exist between the results

I feel like I'm asking a stupid question but.... regarding the example you gave about extroversion: because the "Cronbach's Alpha if deleted" for "enjoying social situations," is it too much to interpret that the item "enjoying social situations" is not a good indicator for measuring extroversion (in this specific example/dataset) altogether? Could it also mean that the other 3 items, though highly correlated to each other, are irrelevant to extroversion and "enjoying social situations" is actually the only appropriate item for measuring extroversion?
@datatab
@datatab 2 года назад
Sorry for the late answer! Yes, your sentence at the end is correct! With Cronbach's alpha, you can only measure the extent to which a group of questions is related to each other. Whether they really measure what they are supposed to measure is not something you can say! Therefore, it is also possible that all three items are very similar but measure something else and the one question only measures the "right thing". Regards, Hannah

2:20 "the condition must be fulfilled... that all questions or items measure the same latent variable" Does that mean that, I can't calculate cronbach's alpha on questionnaires which have a single item for every domain? Thanks!
@dovidasm
@dovidasm 9 месяцев назад
Sounds weird though... Suppose your items (questions) were perfectly correlated, your alpha would be then >=1 (=excellent according to George and Mallery's interpretation). I would find this case undesiderable, it means you were not smart enough to "design" your questions; just knowing the answers of one question would let you perfectly guess the answers of the rest of the questions (?). Imagine this case: no! yes! I love chocolate ☐ ☐ ☐ ☐ ☐ I hate chocolate ☐ ☐ ☐ ☐ ☐
@datatab
@datatab 9 месяцев назад
Yes, you're right! In a good Likert scale, the individual items should not correlate extremely highly with one another!
