• or any other aspect of human or animal behavior

Data collection and entry can be:

• from a stand-alone Windows computer (The Observer Basic)

• from video tape or a video file with on-screen playback controls (The Observer Video-Pro)

Data analysis features

Time-Event Table	- a chronological listing of all recorded events, visualising the change of states and the occurrences of events in the course of time.
Time-Event Plot	- a graph in which observational data are plotted against time, giving a quick overview of what happened and when.
Elementary Statistics	- descriptive statistics on the frequency and duration of events or states, for subjects, individual behaviors, modifiers, and combinations.
Lag Sequential Analysis	- examines how often certain events are preceded or followed by other events, for example how often a certain operation is followed by an error.
Reliability Analysis	- measures the level of agreement between pairs of raters, based on the degree of agreement between the scores in two data files.
Export functions	- exports the summary tables to spreadsheets, databases or statistics packages.
