It outlines methodologies for single-point and multiple-point external standardization, emphasizing the limitations and considerations for each, such as determinate errors. It further delves into unweighted and weighted linear regression techniques, detailing equations for calculating slope and y-intercept while addressing error management.

It discusses absolute and relative errors as measures of accuracy and defines different types of determinate errors, such as sampling, method, measurement, and personal errors. It also explains identifying constant and proportional determinate errors.

Although there may be several different sources of determinate error, each source has a specific magnitude and sign. Some sources of determinate error are positive and others are negative, and some are larger in magnitude and others are smaller. The cumulative effect of these determinate errors is a net positive or negative error in accuracy.

Errors affecting accuracy and precision are addressed through propagation of uncertainty. The page covers probability distributions, normal distribution confidence intervals, and statistical analysis techniques such as t-tests and F-tests for comparing data sets.
