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).
