For my masterthesis I do research about the study progress of college students. I have data about students set in an excel file with the following topics:
column 1: code of student
column 2: sex of the student
column 3: birthyear of student
column 4: nationality of student
column 7: secundary level
column 8: succes rate year 1
column 9: succes rate year 2
I first do optimal matching on the data to have a look which students have +/- the same study progress (looking at secundary level and succes rates). Then I make 3 clusters of students who have a similar study progress. Now I want to know for example the number of male students in cluster 1. The birthyear of the students in cluster 1.
How do I have to compute these in R? Which function do I have to use?
If you have more questions about the code I already used or the datasheet you can ask me.
Thank you for helping
