Accuracy describes the correlation between the measured value and the accepted value. The accuracy of a measurement, or set of measurements, can be expressed in terms of error: The larger the error is, the less accurate is the measurement. Precisiondescribes the reproducibility of a measurement. To evaluate the precision of a set of measurements, start by finding the deviation of each individual measurement in the set from the average of all the measurements in the set: Note that deviation is always positive because the vertical lines in the formula represent absolute value. The average of all the deviations in the set is called the average deviation. The larger the average deviation is, the less precise is the data set.

What did the difference engine do?
calculate long polynomials to high precision by the "method of differences", a technique resembling numerical integration but just involving enormous numbers of additions.
What determins the precision of a calculated result based on measurements?
the precision of the least precise measuement
What is the exactness and consistency of measurements?
Precision
What is the math term that refers to the degree of exactness?
precision
What digit in the number 2801.3 determines precision?
3
How many seconds do stars burn?
The length of time a star burns depends on its temperature and mass. It's certainly not possible to calculate this to the level of precision of seconds, and it's difficult to do so to the level of precision of millennia.
How many digits of pi would you need to calculate the circumference of the known universe to a precision the radius of an atom?
39 decimal places.
Is it true significant digits are the number of digits that reflect the precision of a measurement or number?
No, it is not true. They reflect the precision of the number in the context of its use. If required to calculate the population density of Greater London in 2011, I would use the population in millions - not because that is the limit of the accuracy of the census results but because greater accuracy does not add significant value to the precision of the population density.

What are three steps can you take to insure both accurate and precise measurements?
Calibrate measuring instruments regularly to ensure accuracy. Take multiple measurements and calculate the average to increase precision. Follow proper measurement techniques and minimize sources of error to improve both accuracy and precision.
How can you make a sentence for precision?
