There are several ways to gain access to respondents: face to face, by telephone, by post, online or by other means. Once contact has been made, there are various ways to capture data. A variation of these methods of data collection is the panel, a set of individuals that reports its experiences over a period of time. All of the data capture methods can be made into panels. Observation is a method of primary data collection that involves seeing, tracking or sensing behaviour or actions in some way. It may be hidden or the observed may know. It may be mechanical using visual or audio-recording devices. This approach can be effective when used to identify problems. Mystery shopping and accompanied shopping are forms of observation. http://www.oxfordtextbooks.co.uk/orc/...
