Does age predict performance on the certification exam?
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.
10. Is there a significant difference in knowledge between on-site and off-site workers before they take the training?
11. Is there a significant increase in knowledge as a result of the training?
12. Do participants of different classifications (professional, paraprofessional, and nonprofessional) perform differently on the certification exam? Which group performs best?
13. What are the effects of gender and worksite location (on- or off-site) on level of confidence? In other words:
13. Is there a gender difference in confidence?
13. Does type of worksite experience affect confidence?
13. Is there an interaction between gender and worksite in their effect on confidence?
a. After controlling for prior knowledge, is there a difference between professionals, paraprofessionals, and non-professionals in knowledge after the training?
a. Does age predict performance on the certification exam?
a. In addition to age, does confidence improve the ability to predict performance on the certification exam?
a. Does the distribution of the classifications of participants (professional, paraprofessional, and nonprofessional) differ than what one would expect by chance?
a. 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 four 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.
Assignment 1 Grading Criteria | Maximum Points |
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 short paragraphs describe the intent of your investigation in the form of a problem background and purpose statement.
10 = problem background described 10 = purpose described 5 = relevance to field of study 5 = APA format and writing style |

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 all scale variables. Label your tables and graphs according to APA format. Conclude with a paragraph summarizing the demographic characteristics of this sample.
Displays correct choice of graph or chart and describes sample using correct descriptive statistics 5 = Gender 10 = Age 5 = qualification 5 = worksite 10 = knowledge1 10 = knowledge2 10 = years 10 = confidence 10 = exam 5 = APA format and writing style |

Part IV. Answer FOUR of the nine following research questions. Based on the research scenario and the data, you restate the research question, 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 a summary statement interpreting the results and answering the research question. You should select items so that you present 4 different types of analyses.
24 = Correct hypothesis 24 = Correct choice of statistical technique 24 = Correct tables 32 = Correct summary and interpretation 24 = APA format and writing style Question Breakdown: (32 pts each) 6 = Correct hypothesis 6 = Correct choice of statistical technique 6 = Correct tables 8 = Correct summary and interpretation 6 = APA format and writing style |

Part V. Summarize your results. Summarize the findings and relate them to the stated purpose of the research. This includes a brief summary of the sample characteristics, including (based on your results) interesting differences between groups. Then, discuss what the results say about the effectiveness of the program that would be relevant to the organization’s intent.
5 = Summarize findings 14 = Describe and interpret sample characteristics and differences in knowledge 14 = Interpret results in terms of program effectiveness 4 = APA format and writing style |
