Question

I am working on a method section for a paper. The experiment in general terms is testing to see if there is a significance between two treatment groups in substance abuse recovery. One group is an exercise group the other is not. the sample population is about 100 individuals and 50 in each category. All individuals will be asked yes or no if they relapsed over the last year. What would be the best statistical analysis test for determining if this is chance or if there is significance.

Answer 1

I am working on a method section for a paper. The experiment in general terms is testing to see if there is a significance between two treatment groups in substance abuse recovery. One group is an exercise group the other is not. the sample population is about 100 individuals and 50 in each category. All individuals will be asked yes or no if they relapsed over the last year. What would be the best statistical analysis test for determining if this is chance or if there is significance.

The hypothesis are:

Ho: there is no difference between two treatment groups in substance abuse recovery

H1: there is difference between two treatment groups in substance abuse recovery

You can make the table like this:

		exercise group	No exercise group
Relapse	yes
	no
		50	50	100

The data are categorical. The appropriate test is chi square test.
