To distinguish results based on the only two variables of awareness.
Observed (presence) vs the unobserved (absence) changes the outcome in every experiment.
Something like a control group, if i am on the right side of the road (as in 50 states, but not territories of the US that is us.

Other differences might include how they are defined; and in what cases they are typically used.

Two models are needed to describe light because light behaves both like a wave and a particle. Wave theory is used to describe the wave-like properties of light such as interference and diffraction, while particle theory is used to describe phenomena like the photoelectric effect. Both models are necessary to fully explain the behavior of light in different situations.
The wave model of light and the particle model of light.
two different mathematicians and scientists
Two scientists may have different underlying assumptions that lead them to different conclusions about the same data.
Nissan currently makes two different models of pickup trucks. These models are the Nissan Frontier and the Nissan Titan.
The two models have a similar look and have similar features, but these are two different Samsung phone models.
Scientists use data and models to make accurate predictions. Data provides information on past events and patterns, while models help to simulate and understand how different variables interact to predict future outcomes.
The two types of televisions use different technologies to light up their screens. Price is also different, with LED TV's being less expensive the HDTV's. You cannot get a flat screen LED TV, but you can with HDTV models.
They have gotten different results because they performed it from their knowledge.
No, it will not. These two car belong to different models.
