11F L004 RP Reaction Time 2

Which of the following best describes the relationship between reaction speed and ruler reading in this experiment?

• Slower reaction = smaller ruler reading

• Quicker reaction = smaller ruler reading

• Quicker reaction = larger ruler reading

• Reaction speed does not affect ruler reading

What is the purpose of the conversion table in the reaction time activity?

• To record the number of attempts.

• To convert ruler readings to reaction times.

• To calculate the average speed.

• To measure the length of the ruler.

Why would using an average (mean) not be helpful in this specific experiment?

• It only tells us if, overall, we were better or worse than someone else.

• It shows every individual result.

• It makes the experiment more accurate.

• It helps us see trends over time.

What does "repeatability" refer to in the context of the experiment?

• The ability to get the same result every time without practice

• The ability to measure very small times accurately

• The ability to control all factors in the experiment

• The ability to use high-resolution equipment

Why is the resolution considered poor in the ruler catching experiment?

• The ruler is too long

• Different ruler readings can convert to the same time using the conversion chart

• The experiment is done too quickly

• Only one person is involved

What would improve the reliability of the experiment according to the material?

• Doing the experiment only once

• Using a longer ruler

• Doing the experiment several times

• Not using a conversion chart

What does a computerised reaction test typically ask you to respond to?

• A sound or image

• A written essay

• A physical obstacle

• A mathematical equation

What is the definition of the mode in a set of values?

• The value that is in the middle when the values are written in order

• The value that appears most often in the set

• The sum of all values divided by the number of values

• The smallest value in the set

Given the reaction times: 0.21, 0.14, 0.19, 0.21, 0.21, 0.19, 0.15, 0.16, 0.19, 0.18, what is the mode of this set of results?

• 0.19

• 0.21

• 0.14

• 0.15
