A type of study that observes an individual or measures a specific result. No attempt is made to affect the outcome (for example, no treatment is given).
A very simple example is some kind of research. Suppose someone on a busy street in the neighborhood of New York asks a random passerby for the number of pets and uses that data to determine if more pet food stores should be added to the area.
