Dear candidate,

Data science being a multidisciplinary field, anyone from any engineering stream  or a non engineering field can pursue it. It includes  statistics, probability, linear algebra, Hypothesis Testing, Analysis of Variance & Covariance and a lot of programming using different languages! So if you pursue CSE, it would be immensely beneficial, if you have other streams in mind you can also go for it because one necessarily doesn't have to be a hard core coder or programmer for learning this but yes, having prerequisite knowledge in Java, R, Python/C or staying in a stream of CSE will definitely help you in the long run if you want a career in it.

All the best!
