O First Income Family size Debt O Second income.Explanation / Answer
If we see, the row and columns of Location, the highest absolute value is -0.537 which corresponds to the correlation of location and First Income. So the answer is First Income.
If we see, the row and columns of First Income, the lowest absolute value is -0.063 which corresponds to the correlation of First Income and Family Size. So the answer is Family Size.
