Which should be used after messing up clustered index? Update statistics, Reindex or Reorganize?

Statistics - What test do I perform to try to find a correlation between this data?

• I am in AP Statistics class in high school and we have a final project where we try to find a correlation between two things. I have conducted a simple random sample of about 32 people from my school and asked them for their height, weight, gender, and number of sports they did this year. I took their height and weight and used them to calculate their BMI (Body mass index). I am trying to find if there is a correlation or not between these variables (# of sports they did this year vs bmi). I know how to use each test, but am not sure when to use which one. Therefore, I am kind of confused as to what tests to use for this project. Any suggestions/help would be much appreciated. Thank you!

• Answer:

  If you want to calculate correlation between BMI and joint effect of sports they did this year, use multiple correlation. you can use simple linear/ non linear regression according to your data nature ie normality.it is very easy. use spss.
