Subject:      Intra-class correlation and the aggregation issue???
Content-Type: text/plain; charset=us-ascii

Hello everybody,

I collected questionnaires from individuals working on three departments in different organisations. I seek to know if there are significant differences among the three depts. or not.

I computed mean and SD. But, some researchers argue that the aggregation issue should be considered in this regard and they suggest to carry out intra-class correlation to measure the level of aggregation.

My questions are :

1- what does intra-class correlation mean?

2- how to carry out it using SPSS?

3- is there any alternative test to measure the level of aggregation?

Any thoughts are most welcome,

Best regards,
