Question

14. What is the purpose of doing multiple trials in an experiment?
​

Answer 1

Multiple trials in an experiment are conducted to confirm the reliability of results, to reduce the effect of outliers and anomalies, and to ensure that findings are replicable and valid across different sets of data.

Step-by-step explanation:

The purpose of doing multiple trials in an experiment is to ensure that the results obtained are reliable and not due to random chance. When an experiment is repeated multiple times and consistently yields the same outcomes, it strengthens the validity of the results. This process of repetition also helps to identify any anomalies or errors that might occur if only a single trial was conducted. Moreover, when the experiment is replicated by other researchers and the findings are consistent with the original study, it further solidifies the evidence supporting the hypotheses. Having reproducible results is crucial in the scientific community as it demonstrates that the experiment's conclusions are not an isolated occurrence but are reliable indicators of the relationship between variables involved.

Finally, conducting multiple trials helps in averaging the data to reduce the impact of outliers, thus providing a more accurate measure of the variables being tested. Replication is a foundational principle in experimental science and is a key step in confirming the legitimacy of scientific discoveries.

Answer 2

This question is incomplete as it lacks options, the options are:

A. To get as much data as possible.

B. To make sure the procedure is done correctly every time.

C. Eliminate observations that are not typical and reduce error

D. To double-check the results so they are the same each time

The answer is C.

Step-by-step explanation:

An experiment is carried out to test a hypothesis, which is a predictive explanation/solution to a problem. The experiment aims at accepting or rejecting the hypothetical claim. However, the experiment needs to be conducted more than once, which is called MULTIPLE TRIAL.

An experiment is conducted multiple times in order to improve how accurate the results are. This means that the error in the experimental results is brought to minimal by replicating or doing it multiple times. Hence, the purpose of conducting an experiment in multiple trials is to eliminate observations that are not typical and reduce error
