A farmer applies different fertilizer to his cotton crops, to see which will make his plants grow the highest. What is the dependent variable? A. Type of Fertilizer
B. Height of Plants
C. Weight of Plants
D. Different Cotton Crops

Variables are the measurable quantities in an experiment that can have different values

In the given farmer's experiment, the dependent variable is option B.

B. Height of Plants

The reason the above selection is correct is as follows:

The dependent variable and the independent variable are two types of

variables in a study that seeks to identify cause-and-effect relationships

An example using fertilizer and crop height is presented as follows;

The cause of the observed effect is the independent variable (x) which is

not dependent on the other experimental variables.

The effect which is being observed or measured is the dependent variable

(y).

The farmer intends to see the growth in height of his plants due to the

application of different fertilizers

Therefore;

The effect (of the fertilizer) being observed or measured by the farmer is the height of the plant, which is then the dependent variable

The correct option for the dependent variable is option B. Height of Plants
