Answer 5

Examples to know how to get greatest possible error

for example you use a beam balance to find the mass of a rock sample for a science lab. you read the scale as 3.8g. what is your greatest possible error?
well the rocks mass was measured to the nearest 0.1g, so the greatest possible error is one half of 0.1g

he's right but here's the definition: one half of the unit of measurement to which the measure is being rounded. EX. the greatest possible answer of 3g is 1.5g

If you have 3 cm, you are measuring to the nearest cm, so the greatest possible error would be .5 cm.
