Your question is Statistical Significance Methods. 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).
What methods would you use to ensure statistical significance in your analyses?
Discuss how you would formulate hypotheses, choose an appropriate statistical test, set a significance threshold, assess statistical power, and account for multiple comparisons. Explain how you would validate assumptions and distinguish statistical significance from practical importance. Include how confidence intervals, effect sizes, sample-size planning, and sensitivity checks would support your conclusion.
