Braden wants to compare the types of ducks in two nearby ponds. He collected two samples using the following criteria. For sample 1, he counted the types of ducks on Walden Pond from 6 A. M. to 9 A. M. For sample 2, he counted the number of Mallard ducks that were on Brook’s Pond from 12 P. M. to 3 P. M.

Correct answers are A. B. C.

Braden should sample the ducks on each pond at the same time of day because animals are active at different times.

Braden should sample twice at each pond if he wants to make sure each sample is representative of the population.

Braden should count more than Mallard ducks on Brook’s Pond if he wants to compare the types of ducks on each pond.
