Question: You are testing five fertilizers on the U.T. experimental farm plots along the Tennessee River off of Alcoa Highway. Three of these-TNT, DUH, & PHD-are synthetic nitrogen enhancers. Two-POO & ZOO-are natural fertilizers. You have 48 equal sized plots with equal pre-tested soil nutrients & organics, & plant corn in each plot, using each of the fertilizers on six plots, & retaining six plots for a control group. At harvest, you measure how many pounds of corn you have produced from each plot:

[A] Find the independent variable?

[B] Find the dependent variable?

[C] What is/are the appropriate tests to use for this study?

[D] Are contrasts or post hoc analyses indicated? Why?

[E] Perform the appropriate analysis/analyses & state your conclusions.

POO	ZOO	TNT	DUH	PHD	Control
76	87	65	83	68	62
90	90	80	62	74	57
79	94	68	74	75	62
83	89	81	77	75	65
