Post Graduate distance program in statistics - From where and how helpful will it be?


I want to pursue a career in data science. Currently, I am a final year engineering undergraduate and was thinking about enrolling into a post graduate distance program in statistics. Will it be useful?

What are the universities offering distance program in statistics? I only found a post graduate diploma in operations research by anna malai university? Can you help and also is it worth the time and effort?
Thanx in advance.
