Question

Allied Health - A wound was measured to be 0.8 cm in length. Whaat is the greatest possible error of this weight in grams?

Answer 1

Ok, so

First of all, we got that the wound was measured to be 0.8cm.

This measurement equals to:

0.8cm is equal to 8 millimeters.

Now, the greatest possible error in a measurement is one half of the precision (smallest measured unit).

8 mm was measured to the nearest 1 mm, so the measuring unit is 1 mm.

So, one half of the precision (1mm) is 0.5

Therefore, the greatest possible error is 0.5 mm
