Hi, Swati - you cannot include control variables in a t-test; instead, you would conduct a repeated measures ANCOVA (even though your IV has just 2 levels)
Thank you, Doug. What if I'm comparing mean scores of two people in a dyad or pair situation. For example, lead and assistant teachers' wellbeing. I am trying to control for both teachers' "experience" teaching preschool. In this scenario, can I still use ANCOVA? In this situation my IV is Teacher type. Levels are lead or assistant teacher.
That case might be trickier because you have two separate levels of experience for each teacher rather than a single control variable for the pair (unless you averaged their scores on experience). You might need to consider multilevel modeling/dyadic data analysis which is beyond my scope of knowledge. But perhaps this would be a start: davidakenny.net/dyad.htm
