What are dependent variables?

Back

Dependent variables are the variables that are measured in an experiment and are affected by changes in the independent variable.

Front

What are independent variables?

Back

Independent variables are the variables that are manipulated or changed in an experiment to observe their effect on dependent variables.

On which axis is the independent variable plotted in a graph?

Back

The independent variable is plotted on the X-axis.

Front

On which axis is the dependent variable plotted in a graph?

The dependent variable is plotted on the Y-axis.

Front

What type of graph is best for showing changes over time?

Back

A line graph is best for showing changes over time.

Front

What type of graph is best for comparing different categories?

Back

A bar graph is best for comparing different categories.

Front

What is a controlled variable?

Back

A controlled variable is a variable that is kept constant throughout an experiment to ensure that the results are valid.

Front

What does it mean to manipulate a variable?

Back

To manipulate a variable means to intentionally change it in an experiment to observe the effects on other variables.

Front

What is the purpose of a graph in scientific data?

Back

The purpose of a graph is to visually represent data to identify trends, patterns, and relationships between variables.

What is a claim in scientific research?

Back

A claim is a statement or conclusion that is based on evidence from data.
