TOLERANCE - Usually provide as a percentage of the expected value. It can be plus or minus. Tolerance = (Measured Value - Expected Value)/Expected Value. In the above case the Tolerance is (75.1-75.0) / 75 = 0.13%.
In terms of measurement, the difference between the maximum and minimum dimensions of permissible errors is called the "tolerance." The allowable range of errors prescribed by law, such as with industrial standards, can also be referred to as tolerance.
Tolerance/ Margin of Error
Error in measurement may be represented by a tolerance (margin of error). Machines used in manufacturing often set tolerance intervals or ranges in which product measurements will be tolerated or accepted before they are considered flawed. It is one-half of the precision of an instrument.
Error tolerance means that a product reacts to user's errors. If possible, the product corrects occurring errors independently autonomously. If this is not feasible, the product informs the user and allows easy error correction, while supporting the user as far as possible.
Accuracy determines how close your measurement is to the actual signal value. Precision is the degree to which your measurements vary from one to the next. Tolerance is the pre-determined, acceptable level of that variation in precision.
Tolerating uncertainty means you're able to cope with the fact that you don't know how things will turn out. Signs that you may have a high tolerance to uncertainty include: being willing to take calculated risks. adapting to new environments and processes.
Accuracy = closeness of agreement between a measured quantity value and a true quantity value of a measurand. 2. Error or measurement error = measured quantity value minus a reference quantity value. 3. Tolerance =difference between upper and lower tolerance limits.

5. Tolerance for error. The design minimizes hazards and the adverse consequences of accidental or unintended actions. Example: Educational software provides guidance and background information when the student makes an inappropriate response.
1. an exercise test to determine the efficiency of the circulation. 2. a test to determine the body's ability to metabolize a substance or to endure administration of a drug.
PRINCIPLE FIVE: Tolerance for Error
The design minimizes hazards and the adverse consequences of accidental or unintended actions. It arranges elements to minimize hazards and errors: most used elements, most accessible; hazardous elements eliminated, isolated, or shielded. It provides warnings of hazards and errors.
Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage. In other words, the percent error is the relative error multiplied by 100.
Error or measurement error = measured quantity value minus a reference quantity value. Tolerance =difference between upper and lower tolerance limits. Uncertainty or measurement uncertainty = non-negative parameter characterizing the dispersion of the quantity values being attributed to a measurand.
Britannica Dictionary definition of TOLERANCE. 1. : willingness to accept feelings, habits, or beliefs that are different from your own. [noncount] religious tolerance.
A tolerance interval is similar to a confidence interval but with a key difference: tolerance intervals are estimates of the percent of all individuals in the population that are within some specified range of values.
These are grouped into form tolerance, orientation tolerance, location tolerance, and run-out tolerance, which can be used to indicate all shapes.
Tolerance can be unilateral or bilateral. A unilateral tolerance varies in only one direction, while a bilateral tolerance varies in both directions from the basic size.
For example, understanding and accepting the varying opinions in society about religion or politics (even when you disagree) is tolerance.
If "60 (+0.045 -0.000)" is written on a drawing, "60" represents the reference dimension, and "+0.045 -0.000" indicates the tolerance of the upper and lower limits. In this case, the upper limit is 60.045 and the lower limit is 60.000.
Percentage Error = ((Estimated Number – Actual Number)/ Actual number) x 100.
TUR is defined as: The ratio of the span of the tolerance of a measurement quantity subject to calibration to twice the 95% expanded uncertainty of the measurement process used for calibration.
Donald Wheeler, defines the precision-to-tolerance ratio as the amount of tolerance that is consumed by adjusting the specification limits to account for measurement error. This approach represents what happens in reality with measurement error's impact on the specifications.
Percent error in relation to absolute and relative error
Absolute error is the difference between the hypothesized and the exact value, whereas relative error is when you divide the absolute error by the exact value. For example, you get your percent error by multiplying the relative error by 100%.
If, for example, the measured value varies from the expected value by 90%, there is likely an error, or the method of measurement may not be accurate.
