For my thesis, I am looking at the effect of environmental controversies on the profitability of Chinese and European firms. As part of my exploratory analysis, I have to check whether or not the European countries are similar enough to consider them as 1 group.
I collected data on economic development and cultural dimensions. However, I am unsure which test I can use to check for similarity between the countries. The data looks as follows:
The end goal would be to have a test confirming that the European countries are similar enough to consider as 1 group, and to have a test confirming that the European group is significantly different from China.
If anyone has any idea on which tests I can use for this, please let me know! All help is very much appreciated.
