1. Let's create a table with columns for $x$, $y$, $xy$, $x^2$, and $y^2$. 2. For each participant, you need to provide values for $x$ and $y$. 3. Calculate $xy$ by multiplying $x$ and $y$ for each participant: $$xy = x \times y$$ 4. Calculate $x^2$ by squaring $x$: $$x^2 = x \times x$$ 5. Calculate $y^2$ by squaring $y$: $$y^2 = y \times y$$ 6. Fill in the table with these calculated values for each participant. If you provide specific $x$ and $y$ values, I can help create the full table.
