Response - The outcome being measured. An experimental unit is a single object or individual to be measured. Understanding Experimental Design seeks to provide students with a more realistic understanding. Designing and running a good. 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 6.03.3.
