How to eliminate lurking variables.
I'm conducting my first research study. I'm creating a form that applicants fill out online. I'm having a hard time figuring out how I can eliminate lurking variables.
I read this article that said to control them you "should compare 2 or more treatments" but that didn't make sense to me.
I'm trying to see if unhealthy/ineffective study& homework habits is a reason why students have bad relationships with homework and studying. However, I'm unsure if the results I get from my survey will be helpful
Form Question Examples:
the first question I ask on the form is how would you rate your relationship with homework and studying on a scale from 1-5. 1 being bad and 5 being great.
The next questions or section of questions asks students about there study & homework habits, whether they think they have good study habit or bad study habits.
The third question gives students a list of unhealthy study habits, they choose the studying habits they did and it the grade they did them.
Additionally I wanted ask if opened question are better then multiple choice question (would I benefit more from which one)?
