The image presents a math problem involving the calculation of salary indicators for employees of a company. Here's a breakdown of the content:

### Problem Situation:
The goal is to analyze the monthly net salaries of people working in a company. You are asked to use statistical indicators (mean, median, etc.) to represent the company in the best possible way from two perspectives:
1. As the company's director (likely focusing on a positive image).
2. As an impartial observer (focusing on accuracy).

### Data in the tables:
The two tables represent different salaries and the corresponding number of employees ("Effectif") receiving each salary.

#### Salary Table (Document 1):
- Salaries in €: 900, 1300, 1500, 1700, 1900, 2100, 2500, 2900, 3500, 4500
- Number of employees (Effectif) for each salary:
  - 900 → 3 employees
  - 1300 → 2 employees
  - 1500 → 1 employee
  - 1700 → 2 employees
  - 1900 → 8 employees
  - 2100 → 5 employees
  - 2500 → 3 employees
  - 2900 → 3 employees
  - 3500 → 2 employees
  - 4500 → 1 employee

### Additional Information (Document 2):
It mentions that the "Net monthly salary" is the salary that is actually received at the end of the month.

### To-do:
To answer the question fully, we can calculate different statistical measures such as the **mean** (average salary), **median**, **mode**, and possibly other indicators (quartiles) to present the company in two ways:
- From the perspective of the director: This might involve highlighting higher salaries, such as the average or upper quartile.
- From an impartial observer: This would involve a fairer representation, possibly using the median or mode as they are less affected by extremes.

Would you like me to calculate specific indicators like the **mean**, **median**, or **mode**? I can also elaborate on how these can be interpreted for both perspectives.

Feel free to ask for more details! Here are five questions to extend this topic:
1. How can the mean salary be interpreted in this case?
2. Why might the median salary provide a better understanding than the mean?
3. What is the mode in this dataset, and what does it tell us about the salary distribution?
4. How could you use the range of salaries to represent the company more positively?
5. What is the impact of outliers (e.g., the €4500 salary) on the interpretation of the data?

**Tip:** The median is often considered more reliable than the mean in skewed distributions because it isn't influenced by extreme values.
