Paired t-test
| Глоссарий по стандартизации, контролю и управлению качеством |
A form of the t-test where the data consist of pairs of observations on one set of samples, either before and after experimental treatment, or by two different methods of measurement. this statistical test is often used in analyzing the data from a comparison of methods experiment. information about the systematic error is provided by the bias statistic; information about the random error between methods is provided by the standard deviation of the differences. these estimates will be reliable if proportional error is absent, or if the estimate of bias is only interpreted for a medical decision concentration that is close to the mean of the data. the t-value itself is a ratio of the systematic and random error terms and is useful only to assess whether sufficient data has been collected to conclude that a real difference exists. the t-value should not be interpreted as an indicator of method acceptability.

- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.

Passing-bablock regression, английский
An alternate regression calculation that can be employed when ordinary linear regression may not be reliable. this technique is non-parametric and therefore makes fewer assumptions about the nature of the data. it depends on calculating the slopes of all possible pairs of points, ranking those slopes, and selecting a median value. the correlation coefficient is used as a practical measure of when alternate regression techniques should be applied. when r is less than 0.99 or 0.975, depending on the source of the recommendation, deming regression or passing- bablock regression should be used instead of ordinary linear regression.
Outliers, английский
Discrepant values. values which do not agree with the pattern of the majority of other values. they may be due to mistakes or they may represent a significant finding. when outliers are suspected, it is best to calculate the data set with and without the outlier values. if their presence changes the conclusion drawn from the data, then the experimental results are not reliable. it is possible to apply a wide variety of statistical tests or rules for purposes of rejecting outliers, however, the choice of rules is always subject to argument. it is always better to inspect the data as it is collected during the experiment, identify discrepant values, and determine their cause.
