Your question is Covariance vs Correlation. 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 is the difference between covariance and correlation?
Explain each measure, provide its mathematical definition, and describe how changing the measurement scale affects the result. State the range and units of each statistic, explain why correlation is easier to compare across variable pairs, and identify at least one important limitation of both measures. No dataset or numerical calculation is provided, so focus on the definitions and their practical interpretation.
