Question

In an experiment, a fixed amount of fertilizer was applied to each of 10 plots, and the corresponding yield in pounds of corn was measured. Identify the independent and dependent variables in this experiment.

Answer 1

Independent variable: Amount of fertilizer

Dependent variable: Yield in pounds of corn

Explanation:

The amount of fertilizer is independent variable and yield of corn is dependent variable because yield of corn depends on fertilizers. The effect of fertilizer can be tested by measuring the yield of corn in pounds. The fertilizer can help to increase the yield of crop. Hence, the independent variable is amount of fertilizer and dependent variable is yield in pounds of corn.
