Question

Pea plant clones are given different amounts of water for a three-week period. First pea plant receives 400ml. Second pea plant receives 200ml. Third pea plant receives 100ml. 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. What is the independent variable?
A) the different amounts of water

B) the heights of the pea plant

C) the pea plants

D) the natural ways of receiving water

Answer 1

Answer: The independent variable is the different amount of water. The correct option is A.

Explanation:

A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:

--> Dependent variable and

--> Independent variable.

Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:

--> the height of the plant,

--> the size of the plant,

--> the number of leaves

---> if the plant survived or not (dead).

Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!
