Different types of measurement error is described below

Explanation:

1. Barney measured a tree branch which is 25cm in diameter. But in his results he has written 25mm which is wrong. As 25cm and 25mm is not same. 25cmm=250mm. As we knwo that 1cm=10mm so 25cmm = 25x10mm which is 250mm.

2. Camille was excited when new instrument is showed up at the lab. This is wrong because new instrument is first set up after set up it is tested then we can start work in this instrument.

3. Neville pulled out the bathroom scale to measure the mass of the chemicals he needed it is correct Bathroom scale is used to measure the mass of the chemicals.
