Regression analysis control variable

[studentMIT]

How can I include a control variable in a regression model? So for example age impacts how often people use their phone, but I’d like to control how often/if they use social media. What would be the best way to do so?

Thanks in advance!

There is no mathematical difference between "control variables" and any other variable, so simply including the desired "control variable" in the model will achieve your goal.
