PSYC 515 Wk 7 A1 - STONE Homework Cumulative
SPSS Assignment.
OVERVIEW
HOMEWORK: CUMULATIVE SPSS WORKSHEET INSTRUCTIONS
This worksheet is designed to assess your ability to evaluate research designs, determine the most appropriate
research design, conduct statistical tests using SPSS software, and present research conslusions (including
appropriately formatted figures) using professional conventions. Such skills are fundamental to critically
consuming, evaluating and producing research.
INSTRUCTIONS
Be sure you have reviewed this module’s assigned readings and presentations before completing this
assignment.This includes using ensuring the homework is completed and submitted according to the
instructions, SPSS output and images are legible and relevant, and that basic college level writing skills (e.g.,
grammar, sentence structure) are used in the results write-ups. Answers should be placed where indicated (e.g.,
“ANSWER”). Note: all questions must be attempted to be eligible for full credit.
You will use the M7 Cumulative SPSS Data file (an SPSS data file) to conduct most of the tests in this
assessment. It is located in the folder associated with this assignment.
• Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be
. 05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001).
Remember to check your graphs! You often have to ADD the y – axis title.
• Submit the file as a WORD document (.doc or .docx). Make sure the filename of your submission
includes your full name, course and section.

Background information on the M7 Cumulative SPSS Data
Download the M7 Cumulative SPSS Data file associated with this worksheet. It has coded data that you will
use to design, conduct, and interpret to demonstrate mastery of research methods and. It is updated regularly,
so make sure you download the current file linked this specific term. Here is a description for each variable:
VARIABLE NAMES AND DESCRIPTIONS
GENDER 0 = male; 1 = female
EVENTS number of stressful life events that had occurred in the last year
SATISFACTION average Likert-based (1-5) response to survey assessing workplace satisfaction
(higher indicates higher satisfaction)
ERROR1 this number represents identification of OSHA hazards before completing the
annual OSHA training (higher # = identification of more errors)
ERROR2 this number represents identification of OSHA hazards after completing the annual
OSHA training (higher # = identification of more errors)
EMPLOYEE employee type (1 = sales; 2 = warehouse; 3 = management)
SKILLS1 skills assessment taken within the first week on the job (higher = better skills)
SKILLS2 skills assessment completed after 6 months on the job (higher = better skills)
SKILLS3 skills assessment completed after 1 year of service (higher = better skills)
SALARY1 salary at time of hire
SALARY2 current salary
YEARS number of years employed
PERSONALITY Personality type (1 = Type “A” or 2 = Type “B”)

Cumulative Scenario 1
Using the dataset provided, determine two variables that would be appropriate to assess using a two-group
design to assess a “difference”. It can be between-subjects (BS) or within-subjects (WS) design. Use your
selections to answer the following questions.
Conducting a study to see if there is a difference between Personality
Type and Job Satisfaction
1. Decide on the two variables. List them using the names exactly as named within the SPSS file. For
each, identify the variable type (independent or dependent). For the independent variable, indicate
whether it is BS or WS. For the dependent variable, indicate its scale of measurement (nominal,
ordinal, or scale).
Personality Type, designated as “PERSONALITY” in SPSS is the Independent Variable and BS. Scale of
measurement is Nominal.
Job Satisfaction, designated as “SATISFACTION” in SPSS is the Dependent Variable. Scale of measurement
is Scale.
This is a between-subjects (BS) design because there are different people in each category of personality.
2. State the null and research hypotheses based on the variables you selected, labeling one as the “null”
and one as “research”. Explain why you used a one- or two-tailed hypothesis, noting the grade on that
portion is solely based on the consistency of your justification with your choice of tail type.
Null Hypothesis (H0): There is no significant difference in job satisfaction between different personality
types.
Research Hypothesis (H1): There is a significant difference in job satisfaction between different personality
types.
This is a two-tailed hypothesis. I chose a two-tailed hypothesis because I have no basis for predicting the
direction the relationship will take. I have no reason to guess one personality will have better job satisfaction
to the other. Rather, I want to know whether there is any difference at all between personality types and job
satisfaction. Therefore, I believe a two-tailed test is more appropriate as it tests for the possibility of a
difference in either direction.
3. Paste all relevant statistical output in the space provided below:
I will conduct an independent samples t-test, because there are different people in each category of
personality. SPSS: Analyze, Compare Means and Proportions, Independent Samples T-Test
Test Variable = SATISFACTION Score. Grouping Variable = PERSONALITY
