I need to look at the relationship between the number of counselling self-referrals among students from an institution and the total number of students in the same institution, for each year between 2000 and 2015. I have the number of self-referrals per year and the number of total students in that institution per year. What tests do I use to analyse the relationship between the two? Perhaps linear regression?
I'd be really grateful for your answers!
I'm thinking that a Chi-Square test might also be appropriate, given that I have information on both number of referrals and total number of students per year across all 15 years, according to gender, instrument and programme (undergraduate or postgraduate). Am I wrong in considering a Chi-Square test?
