Why we write the error for 325 as 325+_50? Like explain by steps from where I get to write 50?

Expert Solution

No measurement of a physical quantity can be entirely accurate. It is important to know, therefore, just how much the measured value is likely to deviate from the unknown, true, value of the quantity. The art of estimating these deviations should probably be called uncertainty analysis, but for historical reasons is referred to as error analysis.

The symbol ±, meaning "plus or minus", used to indicate the precision of an approximation (as in "The result is 10 ± 0.3", meaning the result is anywhere in the inclusive range from 9.7 to 10.3), or as a convenient shorthand for a quantity with two possible values of opposing sign and identical magnitude (as in "The roots of the equation x² - 4 = 0 are ±2").

# 50 is an error in result got from any experimental measurement .It can be any type of error like:-

*Presentage error

* RANDOM ERRORS

*ABSOLUTE AND RELATIVE ERRORS

*SYSTEMATIC ERRORS

and so on so forth.....
