A data analyst needs to analyze a sales data set to identify the sales representatives who are selling the most units per month. Which of the following should the analyst perform?

A sales analysis is a broad category that encompasses many types of analyses related to sales data, but "performance analysis" is a more specific and accurate description for identifying top sellers.

A link analysis focuses on understanding relationships and connections between entities, which is not the primary goal when identifying top sales representatives by units sold.

A performance analysis is the most appropriate choice because it specifically focuses on evaluating the effectiveness and efficiency of individuals, teams, or processes against predefined metrics, such as units sold per month by sales representatives. It helps in identifying top performers and areas for improvement.

A trend analysis examines how data changes over time to identify patterns or directions, which is distinct from evaluating individual performance at a specific period.
