Nutrition education programs, which teach their clients how to lose weight or reduce cholesterol levels through better eating patterns, have been growing in popularity. The nurse in charge of one such program at a local hospital wanted to know whether the programs actually work. A random sample of 33 clients who attended a nutrition education program for those with elevated cholesterol levels was drawn. The study recorded the weight, cholesterol level, total dietary fat intake per average day, total dietary cholesterol intake per average day, and percent of daily calories from fat. These data were gathered before and three months after the program. Theresearchers also determined the gender, age, and height of the clients.
