Answer 1

Hello Sir/ Mam

YOUR REQUIRED ANSWER IS OPTION B

When data represents percentage return, we know that the following have these units:

• Mean : Percentage
• Median : Percentage
• Quartile : Percentage
• Standard Deviation : Percentage
• Correlation : No unit.

Hence, using the above explanation, it can be said that everything has unit percentage except correlation which has no unit.

I hope this solves your doubt.
