40. An analyst performing data cleansing on invoice data would like to tally the rows that have an amount paid greater than $100. Which spreadsheet functionality should the analyst use?
Answer: D
COUNTIF is the appropriate functionality for tallying rows with amounts paid greater than $100.
Using the COUNTIF function allows the analyst to count the number of rows that meet a specific criterion, in this case, where the amount paid exceeds $100.
A) Conditional formatting
Conditional formatting is used to change the appearance of cells based on their values but does not perform any counting or tallying of data. Therefore, it is not suitable for the analyst's need to count rows with amounts above a specific threshold.
B) Remove duplicates
Remove duplicates is a function designed to eliminate duplicate entries from a dataset. It does not provide any means to tally or count specific rows based on criteria, making it irrelevant to the analyst's requirement.
C) Filter
While filtering can help in viewing only the rows where the amount paid is greater than $100, it does not provide a direct count of those rows. The analyst would need to manually count the visible rows after applying a filter, which is not as efficient as using the COUNTIF function.
D) COUNTIF
COUNTIF is specifically designed to count the number of cells that meet a certain condition, such as amounts greater than $100. This functionality is ideal for the analyst's task, as it automates the counting process based on the specified criterion.
Conclusion
COUNTIF is the most effective and efficient tool for the analyst's goal of tallying rows with amounts paid greater than $100, as it directly counts the relevant entries. Other options, such as conditional formatting, remove duplicates, and filter, either do not provide a counting function or require additional manual steps, rendering them inadequate for this specific task.
