Welcome to your interview.
The question is on your right: Statistical Significance in Hypothesis Testing. 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 results from an experiment and need to decide whether an observed difference is likely real or could have happened by chance. You are asked to explain the idea clearly to a non-technical teammate.
What is statistical significance, and why is it important in data analysis?
