If a scientist wants to measure the size of a cactus population in the desert valley what method does he use?
A cactus (plural: cacti, cactuses or cactus) is a member of the plant family Cactaceae. Their distinctive appearance is a result of adaptions to conserve water in dry and/or hot environments. If a scientist wants to measure the size of a cactus population in the desert valley, he takes a simple random sample from a region and multiply it by the square area of the entire population.
