Which best describes an experiment?

Biology
1 answer:
AleksAgata [21]3 years ago

A: In a lab a scientist measures the height of roses that received different fertilizers.

An experiment must include variables. The other three are just measurements, but since the scientist is varying the types of fertilizers used, this better describes an experiment. It is also done in a controlled environment (in a lab) which helps to eliminate other uncertainties.

Why is it so important for measurements in an experiment to be accurate AND precise?
Mashcka [7]
The reason they have to be so accurate and precise is because, let's say you were doing a lab or something that was involving chemicals. If you had to put a certain amount of chemicals in your experiment, but when you were doing to the math, you messed up and didn't go back and even bother to fix it, that is a really BIG issue. Because something will probably happen to your chemicals because you might have added to much of something into it. So that's why you always have to be so precise and accurate!
