Errors of observation and systematic errors
Contemporary Physics, 1966Summary Methods of displaying results of repeated measurements, and choice of measures of scatter are considered. It is argued that graphical displays and a 50 per cent probability as basis for expression of errors are simpler than, and in many cases as useful as, any other method.

In this chapter we have discussed various forms of field assessment available for monitoring the quality of a habitat, concentrating on three principal components: vegetation cover, species composition, and vegetation height.

The calculation and publication of the errors in measured altitudes due to tilt of the sextant serve a useful purpose in impressing users more strongly with the need for care than does the unbacked advice to rock the sextant always given in the text-books, and also in indicating that carelessness carries greater penalties the greater the altitude.

Although physics is an exact science, the pointer readings of the physicist’s instruments do not give the exact values of the quantities measured. All measurements in physics and in science generally are inaccurate in some degree, so that what is sometimes called the “accurate” value or the “actual” value of a physical quantity, such as a length, a ...

Observation error specifications
2014Abstract This chapter gives an overview of the specifications of observation errors in data assimilation schemes. In particular, different ways of diagnosing the statistics of these errors are also presented. The evidence of correlations for a given number of observations and the way they can be represented are discussed.

On page 179 of the first volume of the Journal, Commander J. Middendorp, R.N.N.R., discusses the effect on the observed altitude that arises when the sextant is tilted out of the vertical plane, and concludes that the error is a maximum for altitudes in the region of 45; it seems to me that the conclusion is incorrect.
