Required practical: Reaction time (Part 2)

This is the second of two lessons on the required practical investigating the effect of a named factor on reaction time. In this lesson we will be looking at evaluating our results, looking specifically at repeatability and reproducibility.

Quiz:

Required Practical Reaction Time - Part B

The quiz will assess knowledge of the nervous system and evaluating a practical.

Q1.Which of the below is an example of a systematic error?

Misreading the measurement on a rulerDropping the ruler from different heights on each repeatA computer always records the timings 2 seconds too slowA student forgets to stop the timer

1/6

Q2.When we evaluate a method, it is important to always....

State a balanced argument with equal points for and againstOnly state good points about the methodOnly state bad points about the method

2/6

Q3.What does the term repeatable mean?

That if someone else were to follow the method they would record similar resultsThat if someone else were to follow the method they would record very different resultsThat if the same person were to follow the method they would record very different resultsThat if the same person were to follow the method they would record similar results
