    Observation is an approach that involves selecting, observing, listening, studying, touching, and recording the behavior and qualities of living creatures, objects, or occurrences in a systematic manner.
    • Using this strategy, researchers aim to understand behaviors and civilizations by learning to know the people involved and their beliefs, rituals, emblems, beliefs, and emotions.
