Concepts covered include systematic variation, control treatments, replication, and scope of inference. The replication is so important in science. chosen to measure the experimental outcome, expected change in a particular way if the hypothesis is true, and a particular way if they hypothesis is true and a particular but different way if the hypothesis is false -sometimes called outcome variable since their values will change in response to experimental manipulation replication I hope that we continue to use it often even when things return to normal., Congratulations for developing such a high quality chapter.

Discuss why replication is important in experimental design. LEVEL - Upper & Lower Division. Privacy Policy, 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) He decides to first test the hypothesis that birds are eating his berries, and consults with a local expert on how best to prevent the birds from eating berries He has eight fields with 10 rows of berry bushes in each field In one of his fields (depicted below, as viewed from above), he covers half of the rows with nets that will prevent birds from landing on the bushes, and he leaves the other half uncovered Over the course of 8 weeks, he counts the berries harvested from each row of bushes in the test field. Factors are explanatory variables. See Answer. Is it worth the trouble? The procedure for applying variance-based methods in numerical experiments is the same employed in the ANOVA in experimental designs (Box et al., 1978; Santner et al., 2003). 1 Approved Answer. Q36 The farmers experiment was widely considered to be well-designed and well-implemented After 8 weeks, he found no difference between groups, and the berry harvest was still lower than in previous years What can he conclude about his hypothesis?
