In another experiment, fishes were placed in separate aquarium tanks with water coming from three different waterways in Los Baños. Three tanks were filled with water from each source and equal number of fish were placed in each tank. The tanks were refilled as required with water from the original sources. Two plant species known to be bioremediators were tested and compared with a control (no plants). Three tanks were assigned to each of the plant species and the control. After three months, a sample of fish was taken from each tank and evaluated whether the fish contains heavy metals above the threshhold(1) and 0, otherwise. Which is the most appropriate procedure to compare the plant species and the control? A. F-test B. t-test C. Cochran’s Q D. Friedman test
