Front

What does it mean to graph data?

Front

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

Back

A control group is used as a benchmark to measure how the other tested subjects do, ensuring that the results are due to the independent variable.

Front

What is the significance of the x-axis in a graph?

Back

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

Front

What is the significance of the y-axis in a graph?

Back

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

Front

How do you determine the highest value in a pie chart?

Back

The highest value in a pie chart is determined by identifying the largest slice, which represents the category with the most significant proportion.

Front

What is a hypothesis?

Back

A hypothesis is a proposed explanation for a phenomenon, which can be tested through experimentation.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
