Question

Simon and his friends are working on an experiment to determine the most common blood type group in California. Which of these methods would be the best form of data collection?

a. Survey their own family members to find out their individual blood types; this data would represent blood type groups in the entire population of California.
b. Survey an area with a high Latino population to find out the blood type of every individual; this data would represent blood type groups in the entire population of California.
c. Offer a free blood–type testing camp in a school laboratory and collect data; this data would represent blood type groups in the entire population of California.

Answer 1

A free blood-type testing camp in a school laboratory because schools are more diverse than your own family and Latino groups so it would be a better representation of the entire population of California. You go to school no matter you're background or race..

So C is my guess
