Your question is Validating Analysis With Incomplete Data. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to analyze a large dataset with missing, delayed, or incomplete information. How did you decide what data was trustworthy, validate your conclusions, and communicate the remaining uncertainty before a decision was made?
