measurement error: the problem

Measurement error is any difference between a measured value of a quantity and its true value. This type of error is common in scientific experimentation and statistical analysis, where data is collected and analyzed to draw conclusions. Measurement error can lead to inaccurate results and conclusions, as well as unreliable data that can bias research results and decisions. Factors such as the accuracy of instruments, the calibration of equipment, the technique used during data collection, and the data processing and analysis can all contribute to errors in measurement. Since these errors can have serious implications, it is important to understand their causes and take steps to minimize their effects as much as possible.
