The data you need

Layout
Long table
Fields
Investment: text; Risk: number; Return: number
One row is
One investment with aligned risk and return estimates. What is the grain?
Rules
Specify horizon, frequency, annualisation and risk measure. Keep returns as numeric fractions if percentage-formatted.
Optional
Optional size, benchmark or asset class.
Preparation
Validate the input grain and missing values. Specify horizon, frequency, annualisation and risk measure. Keep returns as numeric fractions if percentage-formatted.
Units
Risk and return units must be defined and horizon-aligned; annualised volatility and annual return are different statistics.

Worked example

A risk 10%, return 7%; B risk 18%, return 11%. B offers 4 percentage points more measured return with 8 points more measured risk.
