Reading Tables and Graphs in Science

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the variable that is measured as results during an experiment. It is often placed on the right after the first column in a table.

Front

What is the independent variable in an experiment?

Back

The independent variable is the variable that is changed or controlled in an experiment to test its effects on the dependent variable. It is placed on the x-axis of a graph.

Front

What does the y-axis represent in a graph?

Back

The y-axis represents the dependent variable, which is the outcome being measured in the experiment.

Front

What does the x-axis represent in a graph?

Back

The x-axis represents the independent variable, which is the factor that is manipulated in the experiment.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot. It is used to show trends in the data.

Front

What is a control variable?

Back

A control variable is a variable that is kept constant throughout an experiment to ensure that the results are due to the independent variable.

Front

What is the purpose of a graph in science?

Back

The purpose of a graph in science is to visually represent data, making it easier to identify trends, patterns, and relationships between variables.

Front

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

Back

A line graph is best for showing changes over time, as it can illustrate trends and fluctuations in data.

Front

What is a bar graph used for?

Back

A bar graph is used to compare different groups or categories of data.

Front

What does it mean if a graph has a positive slope?

Back

A positive slope on a graph indicates that as the independent variable increases, the dependent variable also increases.
