Pea plant clones are given different amounts of water for a three week period. The first pea plant receives 400 mL each day. The second pea plant receives 200

mL each day. The third pea plant receives 100mL each day. The fourth pea plant

does not receive any extra water; the plant only receives natural ways of

receiving water. The height of the pea plants is recorded daily. Identify the

independent variable. *

i need to know a number

independent variable: the different amount of water

Explanation:

The independent variable would be the different amount of water supplied to the pea plant clones.

The independent variable is the variable inputted by the researcher during an experiment whose value directly affects the dependent variable. It is the variable that is manipulated during experiments in order to see the kind of effects they produce on another variable - the dependent variable.

In this case, the amount of water supplied to each pea plant would directly affect the height of the pea plants. Hence, the amount of water supplied to the pea plants is the independent variable while the height of the plants is the dependent variable.
