Event sampling - In the event sampling observation method the researcher decides beforehand what events or behavior he will record and which ones he is going to ignore; Time sampling - In the time sampling observation method, the researcher chooses the time when he will observe. Time sampling is a method of collecting data or information in which you watch research participants for a specific amount of time and record whether or not a particular behavior or activity took . The classic example of this advantage is that critical sample can be useful in determining the value of an investigation, while the expert sampling approach allows for an in-depth analysis of the information that is present.
