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 AM to 9 A. M. For sample 2, he counted the number of
Mallard ducks that were on Brook's Pond from 12 PM to 3 PM,
What would improve Braden's plan? Select three options.
Braden should sample the ducks on each pond at the same time of day because animals are active at different times,
O Braden should sample twice at each pond if he wants to make sure each sample is representative of the population.
O Braden should count more than Mallard ducks on Brook's Pond if he wants to compare the types of ducks on each pond.
O Braden should only count Mallard ducks on Walden Pond so he counts the same types of ducks as he does at Brook's
pond
O Braden should include herons and geese in his samples because they also like ponds.
