Error in Calibration Curve Results
As expected, the concentration of the unknown will have some error which can be calculated from the formula below. This formula assumes that a linear relationship is observed for all the standards. It is important to note that the error in the concentration will be minimal if the signal from the unknown lies in the middle of the signals of all the standards (the term goes to zero if )
- is the standard deviation in the residuals
- is the slope of the line
- is the y-intercept of the line
- is the number standards
- is the number of replicate unknowns
- is the measurement of the unknown
- is the average measurement of the standards
- are the concentrations of the standards
- is the average concentration of the standards

Famous quotes containing the words error in, error, curve and/or results:
“You can hardly convince a man of an error in a life-time, but must content yourself with the reflection that the progress of science is slow. If he is not convinced, his grandchildren may be. The geologists tell us that it took one hundred years to prove that fossils are organic, and one hundred and fifty more to prove that they are not to be referred to the Noachian deluge.”
—Henry David Thoreau (18171862)
“Never miss an opportunity to allow a child to do something she can and wants to on her own. Sometimes were in too much of a rushand she might spill something, or do it wrong. But whenever possible she needs to learn, error by error, lesson by lesson, to do better. And the more she is able to learn by herself the more she gets the message that shes a kid who can.”
—Polly Berrien Berends (20th century)
“In philosophical inquiry, the human spirit, imitating the movement of the stars, must follow a curve which brings it back to its point of departure. To conclude is to close a circle.”
—Charles Baudelaire (18211867)
“The ideal reasoner, he remarked, would, when he had once been shown a single fact in all its bearings, deduce from it not only all the chain of events which led up to it but also all the results which would follow from it.”
—Sir Arthur Conan Doyle (18591930)
