A.Why is it important to perform multiple experiment trials?

      After a science experiment, you draw conclusions from your findings. In general, you decide whether the results support or contradict your hypothesis, or prediction. A common concern is whether glitches in preparing, executing or interpreting your study make your findings questionable. Multiple trials allow you to see whether the results of each test, or the trials as a whole, show consistency. Consistent findings reinforce the value of your conclusions.

B If a commercial was aired that claimed a new antacid was able to neutralize 25 times more acid as the TUMS® tablet investigated in this experiment, how would you test this claim?

C.escribe possible sources of error in both Exercise 1 and Exercise 2. Describe possible ways to reduce this error in future experiments.

Explanation / Answer

It is important to perform multiple experiment trials becuase taking the mean value of all the trials minimize the value of errors and uncertinities. which makes the measurement more accurate and precise.
