41. 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?
Answer: C
The analyst should use the Left function.
To extract the first three digits of a zip code, the analyst should utilize the Left function. This function is designed to return a specified number of characters from the beginning of a string, making it ideal for this task.
A) Right
The Right function extracts a specified number of characters from the end of a string. Since the analyst needs the first three digits of the zip code, using Right would not be appropriate in this context.
B) Trim
The Trim function is used to remove extra spaces from text, particularly leading and trailing spaces. It does not extract characters from a string, so it would not assist in obtaining the first three digits of a zip code.
C) Left
The Left function is the most suitable choice as it extracts a specified number of characters starting from the left side of a string. In this case, it will successfully retrieve the first three digits of the zip code, making it the correct option.
D) Lower
The Lower function converts all characters in a string to lowercase. It does not have any functionality to extract characters from a string, so it is not relevant to the task of obtaining the first three digits of a zip code.
Conclusion
The Left function is definitively the correct choice for extracting the first three digits of a zip code, as it directly meets the requirements of the task. All other options fail because they either serve different purposes or do not provide the needed functionality for this specific extraction task.
