Question
What is systematic error? Classify errors into different categories.
✓

Answer

  1. Systematic errors are errors that are not determined by chance but are introduced by an inaccuracy (involving either the observation or measurement process) inherent to the system.
  2. Classification of errors:
    Errors are classified into following two groups:
  3. Systematic errors:
    • Instrumental error (constant error),
    • Error due to imperfection in experimental technique,
    • Personal error (human error).
  4. Random error (accidental error)
