Hi,

You must see your area of interest. If your interest falls in solving problems of people and sorting and  giving suggestions,  then you can opt for Psychology course. If you have interest in Data Science more, then go for that and same applies for the statistics course. If you will select it on the basis of your interest, it will surely be beneficial for long run.
