I am a researcher and I am now interesting about the factor that cause baldness become common in the teenagers.My hypothesis is students in taking excessive caffeine. I decided to do the participant observation in the high school.
Hello, I am a new student.
The whole classmates are the population.
Students listened carefully
It’s now 11p.m ,why you still not go to the bed?
My roommate Charlie is the sample.
I just want to prepare my tomorrow’s classes.
Students that have less hair prefer to buy coffee and they paid too much attention on their school work, baldness is a multiple causation.
