COUNTING POPULATIONS

DESCRIPTION

What are the 3 biggest populations in this pond community?. ACTUAL COUNT. Each member of a population is counted one by one. Which population was easiest to count?. Why?. RANDOM SAMPLES. Make a GRIDCount the total number of squares in the gridChoose one square of the grid at random.Count the population in that one square.Estimate the total population by multiplying the number in one square time the total squares in the grid..

Counting:

Counting: If group one has N choices, and group two has M choices, then there are N  M ways to choose from group one AND then from group two. And &amp; If group one has N choices, and group two has M choices, then there are N+M ways to choose from group one OR group two. Or Joe’s Lunchbox
