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).
|Variable||Label||Measurement Scale||Category Name|
|Gender||Gender||Nominal||1 = Male
2 = Female
|age||Age in Years||Ratio|
|qualification||Professional Qualification||Nominal||1 = Professional
2 = Paraprofessional
3 = Nonprofessional
|worksite||Location of Work||Nominal||1 = On-Site
2 = Off-Site
|knowledge1||Level of knowledge before Training||Interval||N/A|
|knowledge2||Level of knowledge after Training||Interval||N/A|
|years||Years of Experience||Ratio||N/A|
|confidence||Confidence in knowledge||Interval||N/A|
III. Exam Instructions
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 and purpose statement.
