Q3.1. Which of the following statements about good experiments is TRUE? A good experiment must include all possible causal factors in one experimental group. A good experiment must have an experimental group. A control group may be useful but is not critical. A good experiment should include a potentially confounding factor in at least one group. A good experiment includes replication by applying treatments to multiple experimental units. Q3.2. Why is replication important to consider when designing an experiment? Replication allows you to test multiple independent variables in the same experiment. Replication increases confidence that your results apply more widely, not just to specific cases. Replication is necessary to introduce systematic variation into an experiment. Replication increases the chances that a rare result leads you to an erroneous conclusion. Use the following passage to answer the next 4 questions. A farmer who grows blackberries has found his harvest to be lower than usual. He suspects that some animals are eating the berries before he can pick them. The farmer thinks it may be either birds (landing on the bushes to feast on berries) or rodents (climbing the bushes from below to munch on berries).
