1. Histogram: Distribution of Employee Satisfaction
Create a histogram of the satisfaction_level variable. The title
should reflect a key takeaway from the distribution.
Analysis
- Most employees are moderately satisfied.
- The distribution is left-skewed, meaning more employees have higher
satisfaction levels, while fewer employees report very low
satisfaction.
- This suggests a generally positive work environment, though there
may still be room to improve satisfaction for those on the lower
end.
2. Box Plot: Last Evaluation Scores
Create a box plot of the last_evaluation variable. The title should
highlight an important insight about the evaluation scores.
Analysis
- 25% of employees have evaluation scores below 0.56, indicating lower
performance, while 50% are within the range of 0.56 to 0.87, suggesting
that most employees are meeting baseline expectations but have room for
improvement.
- The top 25% of employees are performing at a higher level, with
scores above 0.87, representing the highest performers in the
organization.
- With a median score of 0.72, it is evident that while there is a
group of high achievers, a significant portion of employees are
performing at or below average.
3. Comparative Box Plot: Monthly Hours by Department
Create a comparative box plot of average_montly_hours grouped by
department. The title should emphasize a significant difference or
pattern among departments.
Analysis
- All departments work approximately the same average monthly
hours.
- There is no significant variation for each department’s average
monthly hours.
4. Pie Chart of Frequencies: Attrition by Salary Level
Create a pie chart showing the frequency of employee attrition
(left) for each salary category. The title should point out the
relationship between salary and attrition.
Analysis
- Most employees who have low salaries are more likely to leave.
- Only a small percentage of people who have high salaries leave.
5. Bar Plot of Averages: Average Satisfaction by Department
Create a bar plot displaying the average satisfaction_level for each
department. The title should highlight a key observation about
departmental satisfaction.
