Question

Jay, Kip, and Tia are each measuring the concentration of a solution. They are doing experiments separately. They are all are using a colorimeter—a device used for measuring colors. Jay repeats the experiment five times and takes the average measurement, while Kip performs the experiment once. Tia repeats the experiment three times but chooses one of the measurements instead of the average. The measurements taken by ______ are least likely to contain random errors.

Answer 1

Answer:

Jay's measurements are least likely to contain random errors. By repeating the experiment five times and taking the average measurement, Jay is able to reduce the impact of random errors on the final result. Kip's measurement is likely to be impacted by random errors since he only performed the experiment once. Tia's measurements are also likely to contain random errors as she only choose one of the measurements instead of taking the average.
