“The forecasts were quite accurate, and nobody can say they were surprised by the landfall location and intensity of these storms,” said John Morales, a meteorologist and hurricane specialist ...
A spectrum of methods is presented, ranging from very simple and easily applied techniques to quite accurate and thorough procedures. Comparatively simple methods are presented in complete form, while the more complex methods are often handled by reference to separate treatments.
A measurement system can be accurate but not precise, precise but not accurate, neither, or both. For example, if an experiment contains a systematic error, then increasing the sample size generally increases precision but does not improve accuracy. The result would be a consistent yet inaccurate string of results from the flawed experiment.
George Box. The phrase "all models are wrong" was first attributed to George Box in a 1976 paper published in the Journal of the American Statistical Association.In the paper, Box uses the phrase to refer to the limitations of models, arguing that while no model is ever completely accurate, simpler models can still provide valuable insights if applied judiciously.

"We were given a private tour of the Vatican, and they were quite welcoming, actually, quite helpful," says "Conclave" screenwriter Peter Straughan. "So it was a big research project, really.
He calculated the depth to be 3,962 metres (12,999 ft), a value later proven quite accurate by echo-sounding measurement techniques. [1] Later on, due to increasing demand for the installment of submarine cables , accurate measurements of the sea floor depth were required and the first investigations of the sea bottom were undertaken.
Nevertheless, it is a legitimate and still quite accurate method, and experimental methodologies are described below. The value of the Avogadro constant N A was first approximated by Johann Josef Loschmidt who, in 1865, estimated the average diameter of the molecules in air by a method that is equivalent to calculating the number of particles ...
These algorithms can give quite accurate results for highly periodic signals. However, they have false detection problems (often " octave errors "), can sometimes cope badly with noisy signals (depending on the implementation), and - in their basic implementations - do not deal well with polyphonic sounds (which involve multiple musical notes ...
