Does a Data Scientist need to be better at statistics than a software engineer and better at software engineering than a statistician?
Great question !!!There is no right or wrong answer. Data Science is a multidisciplinary body of knowledge and you never know when you might need a certain skill set. That is why Data Scientists don't work alone but rely on a support team. I am primarily into healthcare domain and don't have much experience about software or IT domains. In my experience being a Data Scientist is all about how effectively you can use the provided tools in your quest for information. Uncovering hidden truths buried deep inside several gigabytes of data is like an Easter egg hunt. Its the challenge that makes it worth doing. A software engineer on the other hand may be the guy who makes these tools but he may not know the applications.
