A control variable is a factor that not of your primary concern but may influence your experiment result. So in data analysis, we usually hold it constant to rule out its effect on the development variable.

I have designed a large-scale survey about the life satisfaction of low-income families in Hong Kong. Is it appropriate to use the electronic survey through mobile phones?
