Lesson 41, Exercises 1–3The following helpful tips are numbered to correspond with
the exercise number to which they refer (a dash indicates that no tips are
needed): NOTE: This
exercise does not use the weighted cases method. Use the data file “as is.”1.
Do a, b, c, d, and e. For letter “e,” this question is
asking specifically about effect size. (2 pts for output and 2 pts each for a–e)2.
———- (2 pts)3.
All homework “Results sections” must follow the example
given in the Course Content document “Writing Results of Statistical Tests in Current
APA Format” (Note: you do not have to refer to a figure). (2 pts)Part 2:1. An
industrial/organizational (I/O) psychologist is helping a company determine the
type of work stations preferred by its employees. The business owner believes
that people who work in different departments may prefer different work station
layouts. In order to examine this claim, the I/O psychologist sets up 3
simulated work stations: private office (PO), semi-private office (SPO), and
open floor plan (OFP). She recruits employees from 3 different departments:
Information Technology, Human Resources, and Marketing. The participants spend
30 minutes in each simulated work station performing general pre-arranged
tasks. At the end of the 1.5 hours, the participants turn in a form on which
they mark which work station they prefer. The results are listed in the table
on the following page. Perform a chi
square test of independence (using an SPSS two-way contingency table analysis)
to determine whether the proportions of work station preferences differ across departments.
Use the weighted cases method.

The steps will be the same as the
ones you have been practicing in Part 1 of the assignment—the only difference
is that you are now responsible for creating the data file as well. Remember to
name and define your variables under the “Variable View,” then return to the
“Data View” to enter the data. (2 pts)
