Hi there,
My study has 2 independent variables (2 diff groups) and 3 dependent variables (3 outcomes). I have created a 7-point likert scale questionnaire with 3 items per dv.
Do i need to apply the Cronbach's Alpha twice? (Eg. One for each group)
Thanks in advance!
Dear researcher,
If the two groups are within the same sample/population (e.g. male and female respondents) you do not have to apply Reliability analysis twice for the same tool. Otherwise, you need to do it twice and compare the results.
Good luck with your research
Hi just to clarify,
i have two different groups exposed to two separate conditions. Yes, the groups consists of females and males. In this case, will i need to apply the reliability analysis twice for each construct (3 constructs in total with 3 items per construct) since they are using a similar questionnaire but just that the constructs are the same. (2 similar questionnaires - one for each group)
Thanks in advance!
Dear researcher,
If you are targeting male and female respondents separately (e.g. targeting girl-school and boy-school) then you have two different samples/populations and probably two research settings. In this case, you need to apply twice, which will increase your research tool credibility.
Good luck with your research
