OAHPERD Vol. 50, April 2013 Jess Florence Oklahoma State University Tim Baghurst Oklahoma State University Abstract Skill related health concepts are an important part of an adolescent’s development. Not only are they important for the overall health of the future adult, they also serve as key determinants in athletic success. However, as a physical educator or coach it is important to determine whether any teaching or coaching imparted is improving these skill related health concepts. Typically, this is accomplished through pre and posttests whereby some intervention or training occurs in-between. Average scores are calculated, and a conclusion is made using these averages. Unfortunately, averages are not the best method for determining improvement, and more complex statistical analysis provides better evidence whether interventions are successful. In the present article, an overview of the importance of developing skill related concepts in adolescents is provided in addition to a step-by-step guide on how to statistically test whether interventions are successful. Using statistical analysis will provide the educator or coach with more robust arguments to support or change training or teaching methods. 35
