In which scenario would TOP N analysis be the best solution?

  1. You want to identify the most senior employee in the company.

  2. You want to find the manager supervising the largest number of employees

  3. You want to identify the person who makes the highest salary for all employees.

  4. You want to rank the top three sales representatives who have sold the maximum


Correct Option: D
Explanation:

To determine the best solution for TOP N analysis, the user must understand what TOP N analysis is and the context in which it can be applied. TOP N analysis is a method of ranking data by selecting the top N items based on a specific criterion. The user should choose option D because it requires identifying the top three sales representatives who have sold the maximum, which is a typical use case for TOP N analysis.

Now, let's go through each option and explain why it is right or wrong:

A. You want to identify the most senior employee in the company. This option is wrong because identifying the most senior employee does not require ranking or selecting the top N employees based on a specific criterion. It only involves identifying one employee based on their seniority level.

B. You want to find the manager supervising the largest number of employees. This option is wrong because finding the manager supervising the largest number of employees does not require ranking or selecting the top N employees based on a specific criterion. It only involves identifying one manager based on the number of employees they supervise.

C. You want to identify the person who makes the highest salary for all employees. This option is wrong because identifying the person who makes the highest salary does not require ranking or selecting the top N employees based on a specific criterion. It only involves identifying one employee based on their salary level.

D. You want to rank the top three sales representatives who have sold the maximum. This option is correct because identifying the top three sales representatives who have sold the maximum requires ranking and selecting the top N employees based on a specific criterion (sales revenue), which is a typical use case for TOP N analysis.

Therefore, the answer is: D.
