Assignment 1: Final Exam
The purpose of this exam is to give you the opportunity to
formulate research questions, run the analyses, and interpret the results of
the statistics covered in this class. , as a single Microsoft Word
document placed in the dropbox. The document must be in APA format.
Please read through the entire exam first.
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).
II. Codebook
Variable Information
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.
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.
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.
