Front

What is the purpose of a hypothesis in scientific experiments?

Back

A hypothesis is a testable prediction about the relationship between variables.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

Front

Why is it important to have a control in an experiment?

Back

A control is important to ensure that the results are due to the independent variable and not other factors.

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.

Front

What is the role of a variable in an experiment?

Back

A variable is any factor that can change in an experiment, affecting the results.
