Question: sampling techniques can be used to estimate physical quantities to...

Question details

Sampling techniques can be used to estimate physical quantities. To estimate a large quantity, you might measure a representative small sample and find the total quantity by "scaling up." To estimate a small quantity, you might measure several of the small quantities together and "scale down." In the following problem, describe an estimation technique. How many stars are visible in the sky on the clearest, darkest nights in your hometown? How could this estimate be made?

A. Try to count all of the stars that you see as best as you can. Usually, if you square the number of stars you counted, it equals the real number of stars in the sky.

B. Divide the sky into small sections. Count the amount of stars in one small section of the sky. Multiply the counted number of stars by the number of sections that the sky was divided into.

C. Try to count all of the stars that you see as best as you can.

D. Divide the sky into small sections. Count the amount of stars in one small section of the sky. Divide the counted number of stars by the number of sections that the sky was divided into.
