CRS Questions

Foundations of Modelling

<ref name="bold">Don't forget, you're supposed to indicate which answers are correct by bolding them! </ref>

Which of the following represents low accuracy but high precision:

A) 5 measurements of a meter stick which measure the length as 100cm, 101cm, 99cm, 98cm, 100cm.

B) 5 measurements of a meter stick which measure the length as 80cm, 79cm, 81cm, 82cm, 78cm.

C) 5 measurements of a meter stick which measure the length as 90cm, 110cm, 109cm, 91cm, 100cm

D) 5 measurements of a meter stick which measure the length as 80cm, 95cm, 50cm, 130cm, 200cm.

<ref name="dif">I like the difference between questions A and B. I'm not sure the others are as clear. Need more info to make change</ref>

Which of the following is likely to have the least impact on a model of a ball dropping:

A) Rate of acceleration due to gravity

B) Size of the ball

C) Height of the ball

D) Whether or not the ball is attached to a parachute


About how many squirrels are on Earlham's "front" campus:

A) 1 to 10

B) 10 to 1000

C) 1000 to 100000

D) 100000+

<ref name="front campus">How do you define "front" campus? I think it might be helpful to give them the area of campus so they're not estimating two things at once. Front campus is the area with buildings on it.</ref>
