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).
