Quantitative data is numerical data that can be measured and expressed with numbers, such as the height of a plant.

Front

What is an independent variable?

Back

An independent variable is the factor that is changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What is a controlled experiment?

Back

A controlled experiment is one in which all variables are kept constant except for the independent variable being tested.

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.
