What is systematic observation? A systematic observation is described as a calculated record of an observation used to support or challenge a hypothesis. For an observation to be effective, it must be free from injustice and repeatable. Systematic direct observation refers to the examination of performance other than behavior that has clearly been stimulated by a pre-established and consistent set of motivations. Physical activity is a meaningful behavior for people of all ages, genders and ethnicities. Systematic observation recognizes both the physical and public environments in which physical activity occurs. According to Mc Kenzie and Van Der Mars (2013), physical activity takes many different forms of physical activity. There are three key components in determining systematic observations (a) establishing which behavior is significantly important to observe (b) determining how information will be collected, organized and examined (questions such as who, where and for how long, under what circumstances and in how many occasions should be determined) and (c) clarify under what conditions which behavior will be evaluated as natural, intrusive or unobtrusive and mechanical. The data collection of the instruments used consists of (a) documentation of procedures and practices (b) experimental tests (c) reliability and validity (d) protocol. It is extremely important that staff are trained to be effective observers. The advantages of systematic observation are (a) it is natural (b) the cause of a particular behavior can be seen (c) a specific type of behavior can be seen in person whereas it would not be seen inside a laboratory. The disadvantages of systematic observation are (a) viewers can alter information (b) people are aware that they are being observed, and (c) external variables that might influence behavior cannot be
