make sure you are keeping a track of what happens with the changes you make you really should do them one at a time though or your research could get confused Will have to post a picuture of my youngest brother he is totally unlike us and looks older but don't tell him that he is still suffering from us three telling him he was adopted all his life the brother on the left (your left) is the manager in a large government department (in I.T.) he is the buddhist the other is a social worker for a large government department that looks into child abuse allegations I just got a job in a government deptartment (must be in the family genes) the little brother who is bigger than us reckons he should have been a pen pusher instead of a mechanic
now back to those variables you need to do one at a time otherwise you won't know which one works then you can do two to see if they have an effect on each other - now you are doing behavioural research hope you get top marks
