An analyst performing data cleansing wants to extract the first three digits of the value in the column for zip code. Which one spreadsheet function should the analyst use?

Rationale

The analyst should use the Left function.

The Left function extracts a specified number of characters from the beginning of a text string, making it ideal for obtaining the first three digits of a zip code value.

A (Right) YOUR ANSWER

The Right function extracts a specified number of characters from the end of a text string. Since the question requires extracting characters from the beginning of the zip code, using the Right function would not yield the desired result, as it would return characters from the end instead.

B (Trim) YOUR ANSWER

The Trim function removes extra spaces from text but does not extract characters. It is useful for cleaning up data but does not assist in obtaining specific digits from a zip code value, making it unsuitable for this specific task.

C (Left) CORRECT

This is the correct choice as the Left function allows the analyst to specify the number of characters to extract from the start of the string. In this case, using Left with a parameter of three will successfully return the first three digits of the zip code.

D (Lower) YOUR ANSWER

The Lower function converts all uppercase letters in a text string to lowercase. While it is useful for standardizing text format, it does not address the requirement for extracting specific digits from a zip code, rendering it irrelevant for this purpose.

Conclusion

To extract the first three digits of a zip code, the Left function is the appropriate choice as it specifically targets characters from the beginning of the string. The other options—Right, Trim, and Lower—either operate on different parts of the text or serve different purposes altogether, making them ineffective for this extraction task.
