How to find the absolute error when given only one value using 1/2 LUM

Answers

Answered by GPT 3.5
To find the absolute error when given only one value, you first need to determine the uncertainty associated with the measurement. In this case, the uncertainty is given as 1/2 LUM.

Next, you need to calculate the absolute error by adding and subtracting the uncertainty value from the given measurement value. This will give you a range within which the true value is likely to lie.

For example, if the measurement value is 10 and the uncertainty is 1/2 LUM, the absolute error can be calculated as follows:

Upper limit = 10 + (1/2)
Lower limit = 10 - (1/2)

Absolute error = Upper limit - Lower limit
Absolute error = (10 + 0.5) - (10 - 0.5)
Absolute error = 10.5 - 9.5
Absolute error = 1

Therefore, the absolute error in this case is 1 unit.
