A good helicopter stays in the air longer, so the response variable would be flight time as measured from when the helicopter is dropped from a height of +2 meters until it hits the floor. The helicopter experiments should be dropped from the same heights. The factors that influence flight time must also be identified. For the paper helicopter, the factors are paper type, rotor length, leg length, and leg width. For this experiment, we chose two factors to be studied, which are rotor length and leg length. After that, answer the following question in the table. 1.The objective of the experiment 2.Response Variable. 3. Factor and Level 4.Randomization
