mean deviation from the mean

Voorbeeldzinnen

1. It is defined as the root mean square (RMS) deviation of the values from their mean, or as the square root of the variance.
2. This statistical method examines the hypothesis that the population standard deviation and mean value for an emission measured with the candidate system do not differ from the standard deviation and population mean value for that emission measured with the reference system. The hypothesis shall be tested on the basis of a 5 per cent significance level of the F and t values.

4. The reference to the classical intervals (mean + 1 standard deviation) and (mean + 2 standard deviations) is useful for assessing the probability of an event: an observation which is less than one standard deviation distant from the expected value has a high probability of being statistically similar to the expected value; when it is between one and two standard deviations distant, its probability is lower, but not abnormally low; when it is more than two standard deviations distant, its probability is quite low, so that it can be termed a ‘rare’ and potentially ‘abnormal’ event [54].
5. If the deviation from the nominal or measured initial concentration is greater than ± 20 %, analysis of the results should be based on the geometric mean concentration during exposure or models describing the decline of the concentration of the test substance (11).
6. If the deviation from the nominal or measured initial concentration is greater than ±20 %, analysis of the results should be based on geometric mean concentration during exposure or on models describing the decline of the concentration of test substance (3)(8).
7. Accuracy is expressed as trueness (difference between the mean value measured for an analyte in a certified material and its certified value, expressed as percentage of this value) and precision (RSDR, relative standard deviation calculated from results generated under reproducibility conditions).

9. (If a zero value is obtained, take the log10 value of the minimum detection limit of the analytical method used instead.)(ii) Calculate the arithmetic mean of the log10 values (μ).(iii) Calculate the standard deviation of the log10 values (σ).The upper 90‐percentile point of the data probability density function is derived from the following equation: upper 90‐percentile = antilog (μ + 1,282 σ).The upper 95‐percentile point of the data probability density function is derived from the following equation: upper 95‐percentile = antilog (μ + 1,65 σ).
10. Based upon percentile evaluation of the log10 normal probability density function of microbiological data acquired from the particular bathing water, the percentile value is derived as follows:(i) Take the log10 value of all bacterial enumerations in the data sequence to be evaluated. (If a zero value is obtained, take the log10 value of the minimum detection limit of the analytical method used instead.)(ii) Calculate the arithmetic mean of the log10 values (μ).(iii) Calculate the standard deviation of the log10 values (σ).The upper 90‐percentile point of the data probability density function is derived from the following equation: upper 90‐percentile = antilog (μ + 1,282 σ).The upper 95‐percentile point of the data probability density function is derived from the following equation: upper 95‐percentile = antilog (μ + 1,65 σ).
11. "Isostatic presses" (2) mean equipment capable of pressurising a closed cavity through various media (gas, liquid, solid particles, etc.) to create equal pressure in all directions within the cavity upon a workpiece or material. "Laser" (0 2 3 5 6 7 8 9) is an assembly of components which produce both spatially and temporally coherent light that is amplified by stimulated emission of radiation. N.B.: See also:"Chemical laser"; "Q-switched laser"; "Super High Power Laser"; "Transfer laser". "Linearity" (2) (usually measured in terms of non-linearity) means the maximum deviation of the actual characteristic (average of upscale and downscale readings), positive or negative, from a straight line so positioned as to equalise and minimise the maximum deviations.
