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