Answer:
For each temperature, repeat the same experiment a few times and report the mean of the readings. Doing so may help reduce the random error in the result.
Explanation:
Random errors are errors due to random variations in the measuring device. For instance, if a stopwatch is used to measure the same amount of time, the readings each time might be slightly different. However, the mean (average) value of these readings should be a good approximate of the true value.
There are a few possible sources of random errors in this experiments. Examples include the stopwatch, the scale, the thermometer, and even the response time of the student. Repeating the experiment a few times for each temperature could help make the average value of the measurements more accurate.
