Civil Service Clerical Ability Practice exam

The example of a data entry mistake is accurately identified with the choice of typing '1,000' instead of '10,000.' This is a specific instance of a numerical input error where the value entered does not accurately represent the intended figure. Misplacing the comma can lead to significant misunderstandings, particularly in finance or data analysis, where precision is critical.

While all other options also represent errors in data entry, they manifest in different ways. For instance, entering a date in the wrong format may still convey the correct numeric value, just in an unclear way. Using incorrect terminology denotes a misunderstanding or misuse of terms but doesn’t directly alter the numeric data integrity. Omitting essential information means that critical data is not provided at all, which affects the completeness of the information but does not constitute a direct numerical misrepresentation. Therefore, the answer highlighting the mistake in numeric representation distinctly highlights the nature of a data entry error.
