What is an independent variable?

Back

An independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

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 a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent 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 repeat experiments?

Back

Repeating experiments helps to verify results and ensure that they are reliable and not due to chance.
