As an organizations EH& S Manager , you must complete a follow-up evaluation for one of your company’s health and safety training courses so you may assess the level of organizational effectiveness of trained personnel. You collect data from a group of 10 employees who are responsible for work involving permit required confined space work. Each subject was observed and the number of unsafe acts was recorded. With this knowledge , you modify the training course content to eliminate prior deficiencies along with adjusting for changes in the workplace. These 10 employees are then asked to participate in a refresher course using these content improvements . At the conclusion of training , you again observe these 10 employees while recording unsafe acts. How would you set up a statistical test to determine if there were any changes in the unsafe acts observed ?
