A farmer learns of a new type of corn that is supposed to have a higher yield of ears. From previous crops, he knows approximately how many ears of corn 10 plants will produce from the original seeds. The farmer decides to plant the new type of corn to determine if the seeds will produce a higher number of ears of corn. He plants the first 100 seeds of the new type of corn seeds in the field he uses for corn. When it is time to harvest, he randomly selects 10 plants and counts the number of ears. The farmer compares the number of ears with the yield he received the previous year from 10 plants using the original corn seeds. Because the new type of corn produced a higher number of ears, he concludes that the new type of corn does produce more ears of corn. Which of the following statements is not true about this experimental design?
Because the farmer used a comparison between the yield of the new type of corn and the yield from the previous corn seeds, the conclusion is valid.
There may be other variables that affected the yield of corn between this year’s crop and last year’s crop; therefore, the conclusion would be suspect.
Because the farmer did not have two groups growing at the same time, one with the new type of corn and one with the original type of corn, the conclusion may be suspect.
