This model explains the that the amount of money is mostly depends on the position, department and manager as well which explains the general rule of salary earned also. Ans 7.

The larger the lift value, the more significant is the correlation between the two variables. It also means that the two variables are independent and have nothing in common, still they show a high degree of association. In the first Rule, performance score=fully meets and terminated for a cause have high correlation. Lift ratio greater than 1 implies that the relationship between the Marital Description= Divorced and employee status=voluntarily terminated is more significant than would be expected if the two sets were independent. Also, the count of 3 shows, the three case where a person was divorced has voluntarily left the organisation. If the employee is able to meet performance score in 90 days, the employee is voluntarily terminated. A lift value greater than 1 implies that the relationship between the Performance score= 90 days meets and employee status=voluntarily terminated is more relevant than would be expected if the two items were independent.
