Data Science Question A Day

This is an accompanying repository for the questions posted on Twitter by the account, Data Science Question a Day. You can follow the twitter account @data_question for daily questions on Data Science, Machine Learning, R programming and Python (possibly in future).

If in case, you find a correction in any of the questions, please do submit an issue request. If you would like to submit a question, please do submit an issue request.

Although this repository contains questions, the purpose of it is to act as a temporary placeholder for storing questions. Future plan is to migrate questions to more robust database and make the questions accessible via a website.
