Explanation:
A decision tree is a graphical representation of alternatives and states of nature
It is a map of the possible outcomes of a series of related choices. It allows an individual or organization to compare and weigh possible actions against one another based on their costs, probabilities, and benefits. They can can be used to map out an algorithm that predicts the best choice mathematically
It starts with a single node, which branches into possible outcomes. Those outcomes leads to additional nodes, which branch off into other possibilities. This gives it a treelike shape
It's <u>true</u> that perception is the organizing, recognition, and interpretation of sensory data in order to represent and comprehend the formation or environment that is being given.
<h3><u>How does perception work?</u></h3>
It takes organization, recognition, and interpretation of sensory data to represent and comprehend the information or environment that is being presented. All perceptions entail neural system impulses that flow through them, which come from chemical or physical activation of the sensory system.
The smell is communicated by odor molecules, hearing is transmitted by pressure waves, and vision is mediated by light striking the retina of the eye. In addition to the recipient's learning, memory, expectancy, and attention, perception is the active interpretation of these signals.
This process of turning low-level information into higher-level information is known as sensory input. The process that follows links a person's concepts and expectations (or knowledge), restorative and selective mechanisms (like attention), and perceptual-influencing perception.
