Question

For the first two objects, I estimated the error by using half the smallest division on my

wooden ruler, 0.5 mm. For the last two objects, I used a metal tape measure which can

expand and contract with changing temperature, just as the wooden ruler can with changing

humidity. For large distances, such as a desk, it can produce a noticeable error, which I

estimated at ±2 mm.

Object Estimate by Eye Measured Value Comments

Mug (height) 22 cm 15.75 ± 0.05 cm I didn’t start off too hot

CD Case 15 cm 14.20 ± 0.05 cm a bit better

Desk 1.6 m 1.524 ± 0.002 m not bad for something so big

Ruler 30.5 cm 30.48 ± 0.05 cm I am the greatest!​
