## There is a statistically significant association between employee departures and receiving a promotion in the last 5 years (χ² test, p < 0.05). Employees who received promotions were less likely to leave.
Employees who did not receive a promotion in the last 5 years are significantly more likely to leave the company. This indicates that career advancement opportunities play an important role in employee retention.

## There is a statistically significant association between employee departures and department (χ² test, p < 0.05). Departure rates vary significantly across different departments.
The department an employee works in impacts their likelihood to leave. Some departments have significantly higher turnover rates than others, with the average turnover rate across all departments being approximately 25%.

## There is a statistically significant association between employee departures and salary levels (χ² test, p < 0.05). Lower salary levels are associated with higher departure rates.
Employees with low salaries are much more likely to leave the company compared to those with medium or high salaries. This suggests that compensation is a critical factor in employee retention.
