For chemistry and other sciences, it is customary to keep a negative value, should one occur. Whether error is positive or negative is important. For example, you would not expect to have a positive percent error comparing actual totheoretical yield in a chemical reaction. If a positive value...

Per cent error lets you see how far off you are in estimating the value of something from its exact value. These errors could happen due to the imprecision of equipment, measurement (human error or tool error), or some adjustments done in calculation methods (rounding off, etc.). There is...
the decision is very difficult whether it should be awarded the chemistry prize or the physiology or medicine prize.” At some point, it has been estimated that about forty percent of both chemistry and physiology or medicine prizes go for discoveries in biochemistry or related to biochemistry. ...
Surrogate endpoints are measures of things like changes in blood chemistry, blood pressure or how hard you can blow into a machine. These are supposed to predict what matters to patients—things like survival and quality of life—and sometimes they do as with drugs for HIV/AIDS that lower vir...
So how would I go about comparing experimental data range to the actual values? Obviously I could just state that the range found experimentally was in close proximity to the printed values, which is what I did. Is there any equations used to calculate the percent error for melting point ran...

At 1 (2) K, the experimentally measured thermal conductivity is 11 (20) percent larger what is expected from equation (4). An additional conduction channel by sound would provide an explanation for the narrow validity of the standard Fermi liquid approach. As the red line in Fig. 4a shows...
They do have a margin of error, as any device can, and can be off as much as .01 percent. What do breathalyzer numbers mean? The numbers are the measure of your blood alcohol concentration (BAC). This is determined by when you blow into the breathalyzer and it evaluates the levels ...
