Stella and John wanted to test for the effects of temperature on the growth of plants. They took 24 plants- 1 was a control at normal room temperature (20 degrees centigrade) and the other 23 were split into these groups: 4-at 21 degrees centigrade 4-at 30 degrees centigrade 5-at 40 degrees centigrade 6-at 50 degrees centigrade 3-16 degrees centigrade 1-at 12 degrees centigrade Measurements of leaf size and number were taken every two weeks. Describe what is wrong with this approach
One, its the portion of samples that are being conducted for each set. The groups are not equally distributed correctly, so the results will not be very accurate at all.
