In physical education teaching, data analysis is always needed to prove what a student does or does not know. The data is important for the teacher to understand what the concepts he or she must re-teach, because most students are not comprehending specific concepts. From my special education standpoint, data is essential to teaching students with special needs. Data to track a student's behavior (ABC chart) or data surrounding a student's progress with activities tailored to help a student reach his or her Individual Education Plan (IEP) goals. I personally use data a lot, because I am an Adapted Physical Education Specialist, and I need to keep track which students are progressing and those that are not. This allows me to change activities, strategies, etc. to help engage and enhance student learning. Listed below are links that can help anyone understand or utilize data analysis, a.k.a Statistics.
