Study Notes

Dependent Variable

A dependent variable is a variable being measured or observed in an experiment, often in response to changes made to an independent variable.

Key Characteristics:

Its value changes in response to changes in the independent variable
Its value is being measured or observed
It is the outcome or result being studied

Example:

In an experiment to see how much water a plant needs to grow, the amount of water given to the plant is the independent variable, and the growth of the plant is the dependent variable.

Types of Dependent Variables:

Quantitative Dependent Variable: A dependent variable that can be measured numerically, such as height, weight, or temperature.
Qualitative Dependent Variable: A dependent variable that cannot be measured numerically, such as color, texture, or flavor.

Importance:

Helps to identify the effect of the independent variable on the outcome
Allows researchers to draw conclusions about the relationship between the independent and dependent variables
