Dear members,
I have a set of ten statements about opinions of benefits of foreign education upon return to home country on scale of 1-5 ( strongly agree to strongly disagree) . It is not developed using Likert scale/ factor analysis method. Given that would my statements be ordinal in nature? And what would method to combine them together as one index of showing benefits of foreign education. And in second case , will the index can be as scale measurement and use t- test.
Thanks in advance
Best regards
If the ten items have not been demonstrated to correlate in a way that is well explained by a common factor (via factor analysis), then I would not combine them.
Strictly speaking, these are ordinal, although many people will treat them as interval-scaled.
Are you trying to develop new inventory/scale? If yes, it should be validated by other previously validated scales, having constructive and other types of validity.
You have a set of Likert-scored items, which could be combined into a scale.Because there have been so many questions here about that topic, I have created a set of resources at:
