For the following experiment, identify the experimental units, the treatments, the response, and the random assignment.
An investment club decided to compare investment strategies. Starting with nine equal investment amounts, three invested in the “dogs of the Dow”—stocks in the Dow Industrial average that had been underperforming relative to the rest of the Dow average. The relative amounts to invest in each of the stocks were chosen randomly and differently for each fund. Three funds invested following the advice of a TV investment show host, again choosing the specific stocks and allocations randomly for the three funds. And three funds invested by throwing darts at a page from the Wall Street Journal that listed stocks on the NYSE, and invested in each of the stocks hit by a dart, throwing a different set of darts for each of the three funds. At the end of six months the funds were compared.
