Independent/Dependent Variables Flashcard

Front

What is an independent variable?

Back

The independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

The dependent variable is the variable that is measured in an experiment. It is affected by changes in the independent variable.

In the statement 'If I increase study time, then my test score will improve', what is the independent variable?

Back

The independent variable is the study time.

In the statement 'If I increase study time, then my test score will improve', what is the dependent variable?

Back

The dependent variable is the test score.

Front

What is the purpose of a control variable in an experiment?

Back

Control variables are kept constant to ensure that any changes in the dependent variable are due to the independent variable.

Front

Give an example of a dependent variable in a study about plant growth.

Back

The height of the plant is a dependent variable, as it is measured to see how it responds to changes in the independent variable (like amount of sunlight).

Front

What does it mean to measure a variable in an experiment?

Back

Measuring a variable means collecting data on it to see how it changes in response to the independent variable.

Front

What is a hypothesis?

Back

A hypothesis is a testable statement predicting the relationship between the independent and dependent variables.

Front

In an experiment testing the effect of fertilizer on plant growth, what is the independent variable?

Back

The independent variable is the type or amount of fertilizer used.

Front

In an experiment testing the effect of temperature on the solubility of sugar, what is the dependent variable?

Back

The dependent variable is the amount of sugar that dissolves.
