What is a constant in an experiment?

Back

A constant is a factor that remains the same throughout an experiment to ensure that the test is fair.

What does it mean to measure a variable?

Back

To measure a variable means to quantify it using appropriate tools or methods to gather data.

What is the difference between qualitative and quantitative data?

Back

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

What is an experiment?

Back

An experiment is a scientific procedure undertaken to test a hypothesis by manipulating variables and observing the effects.
