CHAPTER 1

Error Analysis

An error may be defined as the difference between the measured value and the actual value. For example, if the two operators use the same device or instrument for a measurement, it is not necessary that they may get the similar results. The difference that occurs between both the measurements is referred to as an ERROR. In this topic we will discuss about error calculation in scientific experiment and computation.

  • Introduction to Error
  • Introduction to Precision
  • Stability in Computational Science
