The mistake, committed by interchanging two digits in a numeric held, during data entry, is called

Discuss

Answer & Solution

Answer: Option A

Solution:

A transposition error is a specific type of data entry mistake where two adjacent digits are reversed or interchanged.

Transposition error occurs when, for example, the number 42 is entered as 24.

This error is common during manual data entry and can lead to significant inaccuracies in data processing and analysis.

In contrast, a transcription error refers to a broader range of data entry mistakes, such as mistyping a character or number.

Transposition error is specifically about interchanging digits, making it the correct answer for this question.
