A model is an informative representation of an object, person, system, or concept designed to help understand, explain, predict, or communicate about the original subject. Models can be physical (like a scale model of a ship), abstract (such as mathematical equations representing atmospheric processes), or conceptual (simplified frameworks to grasp complex realities)

Key Characteristics of Models

• Mapping: A model represents something specific, serving as an image or abstraction of an original entity or system.
• Reduction: It includes only selected attributes relevant to the model's purpose, omitting other details.
• Pragmatism: Models are used as practical substitutes for the original in certain contexts, time frames, and for specific purposes

Types of Models

• Physical models: tangible replicas or miniatures (e.g., architectural models, product prototypes)

• Abstract models: mathematical, logical, or computational representations (e.g., climate models, statistical models)

• Conceptual models: simplified frameworks or analogies to explain phenomena or systems

• Person models: individuals who display products (fashion models) or pose for artists (artist's models)

Examples

• A street map is a model of a city's streets, showing relevant features for navigation but omitting others like traffic signs

• A statistical model explains relationships between variables to predict outcomes

• A fashion model displays clothing for advertising purposes

In summary, a model is a simplified, purposeful representation of reality that aids understanding or communication by focusing on relevant aspects of the original subject
