Mary Herald works as an investment counsellor at U.S Bank. Recently, an inexperienced investor asked Herald about clarifying the differences between two top performing mutual funds from the last decade: Precious Metals (Here referred as Metals) and Strategic Income Fund (Here referred as Income). The investor shows Herald the return data he has accessed over the internet, but the investor has trouble interpreting the table. Table A shows the return data for these two mutual funds for the years 2000-2009; the data, labelled Fund Returns.

Table A: Returns for the Metals and the Income Funds, 2000-2009
