Johnathan is measuring time using a clock. For each measurement, he stands at the same angle. Will the time he measures average out ?

• Yes because it is a random error

• No, because it is a systematic error.

• Yes, because we can find the average of time.

• No, because the average time will be the same as the last time.

In an experiment, a man records the time it takes for an athlete to run 100m . To reduce the effects of errors, what should the experimenter do?

• Have the athlete run 3 laps each day for a week. Then find the average of the times.

• Have the athlete run 30 consecutive laps then find the average time.

• Take the fastest time and the slowest time then find the average.

• Take the median time.
