I would like to conduct multigroup moderation analysis using AMOS. I have two samples. the first one n =73 whereas the second is 216. Are the two sample sizes appropriate for such analysis?
It should be noted that my overall or total sample size is 289. the two samples are categorized according to the quality of ties with organizational leadership. the smaller sample size represents the group which has a negative tie with leadership. usually negative ties are much smaller in number than the positive ties.
I think if you want to use Amos the Sample size for each group should to be more than 200 cases. According to Kline (2011) a typical sample size in studies where SEM is used is about 200 cases. However, a sample size of 200 cases may be too small when analyzing a complex model.
Thanks!
my sample size is 289, but I consider conducting multi group moderation analysis. I wonder if the two samples are adequate.
Try it. if the size is too small AMOS will let you know. However how could you increase the sample sizes without redoing the data collection? Proper Prior Planning Prevents Poor Performance is a good idea to live by. Best wishes, David Booth
Thank you David @ but how will amos tell me if the sample is too small.
I think you can do it by using AMOS, but SmartPLS is another software that is not sensitive to sample size.
the problem with first group.
first one n =73 less than 200
Yes, as Dr. Omid said SmartPLS is another software that is not sensitive to sample size.
