The 3 results should be within ± 0.5.

Question

I have 3 results
1) 1.5
2) 0.5
3) 1.0

Does this mean the results are acceptable since the 3 values can be arranged in the following order
0.5,1.0,1.5.
The smallest value 0.5 is (-0.5) of the middle value 1.0 and the largest value 1.5 is (+0.5) of the middle value.

Thanks!
