Andy is studying the effect of sunlight on the growth of plants. He selected three identical plants with a height of 15 cm for t
he experiment. Andy created a data table for his observations. The first plant was kept away from sunlight, the second plant received 3 hours of sunlight, and the third plant received 5 hours of sunlight. All other growing conditions of the plants were kept constant. Which step of the scientific method will most likely come next?
A hypothesis is first coined before the experiment is conducted. Usually is a null hypothesis of no change. In this case it would most probably be ‘The is no relationship between the amount of sunlight that a plant receives and it's growth’
After the experiment, the observed data is collected and analyzed using statistical methods. The result of the data will determine where the null hypothesis will be adopted or rejected.
Research is done way before the experiment is conducted to provide headway.
