The management of a large firm would like to know something about employee
morale and the other variables to which it may be related. To study these
relationships, each employee in a simple random sample of 27 employees is
interviewed and tested to obtain information concerning morale level and the
average number of satisfying extra work social contacts experienced during a
week. Whether or not the duties the employee usually performs are appropriate to
the job title is also determined.
The dependent variable Y is measure of morale, the quantitative independent
variable, X1 is average number of social contacts, and the following dummy
variable coding is used to quantify the qualitative variable:
X₂ = 1 if yes,
X₂ = 0 if no.
