The Importance of Repeated Trials

• My experiment took a total of 7 days, 6 of them consisting of trials. The first 3 days I placed the fish in bowls with standard room temperatures and I recorded their respiration rates. The next three days I lowered the temperature of the water in the bowl to see how their respiration rates have decreased. In total I spent three days with each kind of temperature. 
• Repetition is crucial when testing a hypothesis. If I were to only have calculated the respiration rate once, then my calculations would not have been very accurate. However, if I were to test them multiple times I can get a more constant result and figure out an average. Repetition helps prove the worth of the data collected.
