Question

After running an experiment, Diego realized that the scale he had used to make his measurements was broken. His lab partner, Will, said not to worry, since they had done everything else correctly, their experiment was still valid. Diego is not so sure. What is true about their experiment? A) The experiment is valid. B) The experiment is not valid. C) The data is not reliable, but the experiment is. D) The validity depends on how broken the scale is.

Answer 1

The experiment done by Diego and Will was done using the broken measurements. The broken measurements would have caused them to collect wrong data. The collection of the wrong data will have disrupted their results. The data is crucial for an experiment as the whole conclusion is dependent on the data collected. Even if the whole experiment is done carefully, the wrong data will lead to misinterpretation of the result. The experiment procedure will be correct but the data will be not.

Hence, the answer is 'option c - the data is not reliable but the experiment is'.
