Question

A student is performing an experiment and takes various values of a quantity P. He is given the information that the uncertainty ΔP in P satisfies ΔP/P = 0.05

Consider the data values given in the table below. For which points of the data set wrong uncertainties are given?

Data points for P

A	B	C	D	E
1.70±0.09	2.3±0.1	4.8±0.2	7.5±0.3	10.2±0.6

Answer 1

Here we are already given the information that the uncertainty in P is 0.05.

That means the maximum error allowed in your measurements is your uncertainty value.
