Type the correct answer in the box. 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.

Explanation:

All experimental measures are subject to errors.

Even when the colorimeter is properly calibrated and correctly used, there are random errors.

Random errors are are due to fortuitous factors, such as minor oversight by the observer or small changes of the conditions under which the measurements are made.

You can minimize the random errors by increasing the number of measurements, because the random errors tend to happen in any direction; some measures will be greater and other will be less than the true value.

Chance will make that errors in on direction cancel with errors in the opposed direction, making the average the best measure.

Thus, Jay, by repeating the experiment five times and taking the average measurement, is making that his measurements are least likely to contain random errors.
