What is research question?What is research Hypothesis?Explain

Hello dear Writer,
Thank you so much for your help with this project, it was great references that you made for two previous articles (I’m attaching them ). I need 3 more bibliography references to attached PDF articles, each is one page long, if possible can you please include information about independent and dependent variables.

And I also I need your help to choose final topic for research proposal that ,I hope, we can work together next month.

It should be about one page long and cover following:
1)What is research question?
2)What is research Hypothesis?
3)Design of the study:
Correlational or experimental?
Who are the subjects?
What variables it will assess?
Method of assessing?(Questionnaire ,performance test ,etc.)
***It is not real research, so it no financial or sample size limitations***
My original thoughts on the topic was “Effects of ballroom dancing on patients with Depression “
