Absolute error and relative error are two types of experimental error.
Alternatively, you may have a known or calculated value and you want to use absolute error to express how close your measurement is to the ideal value.
Here absolute error is expressed as the difference between the expected and actual values.
Absolute Error = Actual Value - Measured Value For example, if you know a procedure is supposed to yield 1.0 liters of solution and you obtain 0.9 liters of solution, your absolute error is 1.0 - 0.9 = 0.1 liters.
You first need to determine absolute error to calculate relative error.
You think that the spark between the two of you is palpable, but at the same time you're not sure if you're on an actual date.
When you first get together with a potential romantic partner, confusion about whether you're on a date or just hanging out is common.Sixty-nine percent of 18-to-59-year-olds reported feeling this ambiguity in a survey by USA Today.Knowing the differences can prevent miscommunication and save you from embarrassment or disappointment.Relative error expresses how large the absolute error is compared with the total size of the object you are measuring.Relative error is expressed as fraction or is multiplied by 100 and expressed as a percent.Relative Error = Absolute Error / Known Value For example, a driver's speedometer says his car is going 60 miles per hour (mph) when it's actually going 62 mph.
