1a. Create a Box Plot for employee satisfaction, each broken out by
the variable left.
Employees who left the company had significantly lower satisfaction
levels with a median satisfaction level around 0.5, while those who
stayed had a median above 0.7, indicating a clear disparity in job
contentment.
1b. Create a Box Plot for last evaluation, each broken out by the
variable left.
Employees who left the company showed a broader range of evaluation
scores compared to those who stayed, whose evaluations were concentrated
above 0.6, suggesting that performance might have contributed to
attrition.
2. Using the HR_comma_sep dataset, create a correlogram, only for
continuous variables.
The number of projects and average monthly hours show a moderate
positive correlation (0.42), while satisfaction levels have little to no
correlation with other variables.
