Data Science – 175 Probability & Statistics Interview Questions

data science interviews

This article presents URL and short description of around 175 probability & statistics objective questions which could prove very useful and helpful for those who are planning to attend one or more data scientist interviews in time to come. These tests/quizzes were created when I was learning probability and statistics some time back and, found various concepts interesting enough to be converted into quizzes for my future references. As probability & statistics form key to data science, it may be worth spending some time on these tests and check your understanding. You may also use this for your future reference. These questions could also be used for checking your concepts around probability and statistics fundamentals in case you are appearing for probability and statistics exams/tests in near future in your school/college.

Please feel free to comment/suggest. Also, sorry for the typos.
