you plan an experiment to test the growth of beans using three different fertilizer. What are the dependent and independent variables in the experiment?

The independent variable is the different fertilizers.

In this experiment, the dependent variable is the growth of the beans. The dependent variable is the outcome or the result that you are measuring or observing. In this case, it is the growth of the beans, which could be measured by the height of the plants, the number of leaves, or any other relevant growth parameter.

On the other hand, the independent variable is the factor that you are manipulating or changing in order to observe its effect on the dependent variable. In this experiment, the independent variable is the type of fertilizer used. By using three different types of fertilizer, you can test how each type affects the growth of the beans.

To summarize:

Dependent variable: Growth of the beans (measured by height, number of leaves, or any relevant growth parameter)

Independent variable: Type of fertilizer (three different types)

By manipulating the independent variable (fertilizer type), you can observe and measure its effect on the dependent variable (bean growth).

In the experiment to test the growth of beans using three different fertilizers, the dependent variable is the growth of beans. This variable is dependent on the independent variable, which is the type of fertilizer used.
