Plz me 50 points how are precision and accuracy different? do a paragraph plz

Precision is how exact a measurement is. To be more precise, you need to have more significant digits. Only decimals have significant digits. For example:

45.5653 ft

There are 4 significant digits because after the whole number, there are 4 numbers.

Accuracy is the closeness of a measurement to the actual value of what is being measured.

Some measurements can be accurate but not precise, and others can be precise but not accurate, Some can be neither, or even both.

If you have any questions, feel free to ask! :)

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
