Justeringsmetoder refer to a variety of techniques used to correct or refine measurements, estimations, or calculations. These methods are crucial in fields where precision is paramount, such as science, engineering, statistics, and finance. The primary goal of adjustments is to minimize errors, account for uncertainties, and produce the most reliable and accurate results possible.

One common type of adjustment is statistical adjustment. This involves using mathematical models to improve the accuracy of data. For instance, in regression analysis, adjustments are made to account for the influence of independent variables on a dependent variable. Smoothing techniques, like moving averages, are also used to reduce random noise in time-series data.

In surveying and geodesy, adjustment methods are fundamental to determining precise positions of points on the Earth's surface. Least squares adjustment is a widely employed technique here, where observations are weighted according to their reliability, and a solution is found that minimizes the sum of the squares of the differences between observed and adjusted values.

Calibration is another form of adjustment, particularly relevant for instruments and equipment. When a measuring device shows a consistent deviation from the true value, calibration involves adjusting the device or applying a correction factor to ensure accurate readings.

The choice of adjustment method depends heavily on the nature of the data, the type of errors present, and the desired level of accuracy. Understanding and applying appropriate adjustment methods are essential for drawing valid conclusions and making informed decisions based on collected data.
