Do Exercise 12.2 Part a

 

12.2 Identifying Good System Administrators. A

management consultant is studying the roles played by

experience and training in a system administrator’s ability

to complete a set of tasks in a specified amount of time. In

particular, she is interested in discriminating between

administrators who are able to complete given tasks within

a specified time and those who are not. Data are collected

on the performance of 75 randomly selected

administrators. They are stored in the file

SystemAdministrators.xls.

 

Using these data, the consultant performs a discriminant

analysis. The variable Experience measures months of

full-time system administrator experience, while Training

measures number of relevant training credits. The

dependent variable Completed is either Yes or No,

according to whether or not the administrator completed

the tasks.

 

a. Create a scatterplot of Experience versus Training using

color or symbol to differentiate administrators who

completed the tasks from those who did not complete

them. See if you can identify a line that separates the two

classes with minimum misclassification.
