Assignment 1: Final Exam SPSS



Assignment 1: Final Exam

The exam consists of three sections

I. The research scenario—to provide the context for the data. Please note that the data are
“content-neutral,” i.e., they do not refer to a specific discipline or field.


II. The codebook—this identifies the variables (names, labels, and
measurement scale) in the database.

III. The exam instructions—for completing the exam. Be sure to
read each question carefully and answer each question completely.

I. Research Scenario:

An organization wants to know if participants with varying levels
of expertise (professionals, paraprofessionals, and nonprofessionals) improve
their knowledge after completing a training program.

The organization collected demographic information: gender, age,
type of training (professional, paraprofessional, or nonprofessional), location
of the worksite (on-site or off-site) and years of experience.

A pre-training test of knowledge, a training program, and
post-training test of knowledge was developed. Participants were tested, then
participated in the three-week training program, and then were tested again.

The dataset also includes (1) a measure of participant confidence
in knowledge and (2) a certification exam score.

The data are discipline-neutral. Therefore, part of your final
project is to create a context for the research that is associated with your
discipline or area of interest (e.g., training to assess mental health status;
training to work with special education children; training to become a
technician or consultant).

III. Exam Instructions

Overview

Your task is to review the dataset, formulate a context, and then use your
knowledge of statistics to answer the research questions and test hypotheses
that will help the organization evaluate the effectiveness of the program.

Part
I. Create your context.

Using
the research scenario and variables identified in the codebook, create a
“story” that describes the purpose and focus of the study. In a few paragraphs
describe the intent of your investigation in the form of a problem
background
 andpurpose statement.





Part
II. Describe your sample.

Generate
frequency tables and bar charts for the nominal variables. Generate and
interpret descriptive statistics of central tendency, variability, skewness,
and kurtosis for the continuous (scale) variables. Generate frequency tables
and histograms with the normal curve superimposed for each scale variable.
Label your tables and graphs according to APA format. Conclude with a paragraph
summarizing the demographic characteristics of this sample.

  1. Gender (nominal)
  2. Age (scale)
  3. Qualification (nominal)
  4. Worksite (nominal)
  5. Knowledge1 (scale)
  6. Knowledge2 (scale)
  7. Years (scale)
  8. Confidence (scale)
  9. Exam (scale)


 

Part
III. Describe relationships among the variables.

Select
the variables that are measured on interval or ratio scales. Create a
correlation matrix.  Label the table according to APA format. Identify and
discuss the strongest and weakest correlations.

Part
IV. Answer any FOUR of the nine following research questions.
Clearly identify which question(s) you have selected to answer by writing the
number associated with the question (1-9) before each answer. Make sure to
select four questions that must be answered by 4 DIFFERENT tests.
For example. One t-test, one ANOVA, one regression and one chi-square; NOT a
single sample t-test, independent sample t-test and paired sample t-test as
these all fall under t-test.

Based
on the research scenario and the data, restate the research question, identify
the Independent and Dependent Variable(s), formulate the hypothesis, conduct an
analysis, and interpret the results for each of the following. Please use the 7
step hypothesis testing model for each analysis, including an APA-style
conclusion statement summarizing the findings, interpreting the results and
answering the research question.

  1. Is there a significant
    difference in knowledge between on-site and off-site workers before they
    take the training?
  2. Is there a significant increase
    in knowledge as a result of the training?
  3. Do participants of different
    classifications (professional, paraprofessional, and nonprofessional)
    perform differently on the certification exam? Which group performs best?
  4. What are the effects of gender
    and worksite location (on- or off-site) on level of confidence? In other
    words:


    1. Is there a gender difference in confidence?
    2. Does type of worksite experience affect confidence?
    3. Is there an interaction between gender and worksite in
      their effect on confidence?
  1. After controlling for prior
    knowledge, is there a difference between professionals, paraprofessionals,
    and non-professionals in knowledge after the training?
  2. Does age predict performance on
    the certification exam?
  3. In addition to age, does
    confidence improve the ability to predict performance on the certification
    exam?
  4. Does the distribution of the
    classifications of participants (professional, paraprofessional, and
    nonprofessional) differ than what one would expect by chance?
  5. Does the distribution of the
    classifications (professional, paraprofessional, and nonprofessional)
    differ from the State data reported as 15%, 25% and 60%?


Part
V. Summarize your findings.

Synthesize
the results of your five analyses. Include a brief summary of the sample
characteristics and the major findings. Interpret the findings so that the
organization’s leaders will have an understanding of the similarities and
differences in knowledge, and how effective the training program is in
improving knowledge.

All
written assignments and responses should follow APA rules for attributing
sources.
