The independent variable in the experiment is amount of coffee grounds. The dependent variable is the taste of coffee. The control variables are; kind of coffee, type of water and perking time.

The independent variable in an experiment is the variable that is being manipulated in the experiment. Changes in the independent variable results in changes in the dependent variable. The control variables are those variables that must be held constant in order to obtain meaningful results.

In this case, the independent variable is amount of coffee grounds. Its effect on the dependent variable which is taste of coffee was studied in the experiment.

Controlled variables such as kind of coffee, type of water and perking time were all held constant.

Answer from: kayltosh2729

Independent variable: The amount of coffee grounds.
Dependent variable: The taste of the coffee.
Controlled variables: The kind of coffee, the same percolator, the same amount and type of water, the same perking time, and the same electrical sources.

Explanation:

In an experiment the independent variable is the variable that you change, the dependent variable is the variable that you are testing to see if it will change because of the change you made, and the controlled variables are the variables that stay the same.
