Graphing in Science

Front

What is a dependent variable?

Back

The dependent variable is the factor that is measured in an experiment, which changes in response to the independent variable. For example, in an experiment measuring plant growth, the height of the plant is the dependent variable.

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable. For example, the amount of sunlight a plant receives can be an independent variable.

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 allows for easy visualization of trends.

Front

What type of graph is used to compare different categories?

Back

A bar graph is used to compare different categories, allowing for easy comparison of values.

Front

What type of graph is best for displaying percentages?

Back

A pie chart is best for displaying percentages, as it shows the parts of a whole.

Front

What does the X-axis represent in a graph?

Back

The X-axis typically represents the independent variable in a graph.

Front

What does the Y-axis represent in a graph?

Back

The Y-axis typically represents the dependent variable in a graph.

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.

Front

How do you determine the scale for a graph?

Back

The scale for a graph is determined by the range of data being represented and should be evenly spaced to accurately reflect the data.

Front

What is a pictograph?

Back

A pictograph is a graph that uses pictures or symbols to represent data, making it visually engaging and easy to understand.
