Selen Ozbek I guess if the choice of company is a nominal/ categorical variable with a scale (mindfulness), you can use Multinomial logistic regression (also called multinomial regression). This analysis is often used to predict a nominal dependent variable (company choice) given one or more independent variables (mindfulness).

Thanks Gulnaz, though it didn't make sense to me because for multinomial regression the dependent variable needs to have more than 2 options, mine has only 2. I tried binary logistic regression but it also asks the covariate (predictor) to be categorical :( really confused!

In that case you are left with two options: Kendall's Tau and t-test.
