Welcome to your interview.
The question is on your right: Diagnosing Unexpected Dataset Results. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You are reviewing a dataset that produced results you did not expect. The first pass looks inconsistent with prior runs, and you need to figure out whether the issue is real, random, or caused by the data itself.
If given a dataset with unexpected results, how would you analyze it?
