# Statistics: Which test to use to find the relation between two binary variables adjusted for a continuous and two binary covariates? How do I check for covariates in the first place?

Asked by kounoupi (680 ) 3 months ago

Still trying to figure stats, bear with me
OK. My data
1) My outcome variable (Outvar) is binary (yes/no)
2) My explanatory variable (exvar) is also binary (yes/no)
3) I have 3 variables:
Variable A is binary
Variable B is continuous but not normally distributed
Variable C is also continuous and has normal distribution
For the varA, varB and varC, I want to check if they impact my outcome variable. If they do I want to “remove” their impact because I want to know the independent impact of my exvar on outvar. Which test should I use?
And, do I need to check the impact of varA, varB, var C on my exvar too?

this may be easy but I am so unable to think right now
if it is of any importance I am using the SPSS v20 for creating all these statistic questions in my head

~ Do you have an English translation Equation?
Maybe the Quadratic Equation -b + – 4ac over 2a.
Breathe in and breath out. when you relax the answer will come.

My first thought is logistic regression.

Thank you for your answers. I am still confused; if I figure this I will post what I did :)

@glacial I am thinking the same, maybe multiple linear regression but I hesitate. Not sure why.
@PhiNotPi wow that site is awesome. I bookmarked it! Also I posted the question there, hopefully I’ll get an answer from someone who can think clearly :)
