Jay, Kip, and Tia are each measuring the concentration of a solution. They are doing experiments separately. They are all are us
ing 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. NextReset
The measurements taken by Jay are least likely to contain random errors.
When you increase the number of measurements, the random errors tend to minimize, because errors in one direction cancel with errors in the opposed direction.
