Two groups of students test the same wind-up toy. each
group conducts four trials to find out how long it takes the
toy to travel 1 meter. study their data in the table above and
answer the questions.
find the average time for each group's four trials.
b. estimate the average error for each group.
c. which group had the best precision? explain.
d. what was the resolution of the stopwatch?
e. the group averages are quite different. are they
significantly different? explain, and use a very simple math problem to prove your answer.
f. one group actually had the windup toy travel down a ramp for 1 meter and the other group had their toy travel across a flat surface. which group was which explain how you know
