Aangrenzende tekens zijn van positie verwisseld.

Transposition errors occur when two adjacent characters swap positions. This is one of the most common data entry errors, often caused by typing too quickly or by dyslexia. Examples include typing '1324' instead of '1234' or 'hte' instead of 'the'. These errors are subtle because all the correct characters are present.

Original: ABCD → Error: ABDC (C and D swapped)

• 12345 → 12435 (3 and 4 transposed)
• ABCDEF → ABDCEF (C and D transposed)
• AB-1234 → AB-1324 (2 and 3 transposed)

Zo herkent u het

• Same characters, but two adjacent ones are in reversed order
• Length remains the same
• Often occurs in the middle of strings

Veelgemaakte fouten

• Confusing transposition with substitution
• Missing subtle swaps in long strings
• Not checking adjacent pairs systematically
