I’ve already written a paper. It’s a descriptive statistical project. I need to edit the Introduction section and I’m struggling with stating the hypothesis. I have attached my paper and the pdf file with instructions. All calculations were made for two psychology fields (educational psychology and counseling). It took two variables (debt and salary variables). Feel free to use more sources. Thank you in advance!
