Question

Most of the modelling is done using:
O Diagrams
O Decision trees
Presentations
O Graphs​

Answer 1

The correct answer is "diagrams".

• Modelling is a scientific activity that aims to make a particular thing easier to understand, define, visualise and relate with existing knowledge.
• Since the easiest way to make something easily comprehensible is to present them visually in the form of a 2-dimensional replica, a diagram is the most suited for the purpose.
• A diagram is a basic sketch of anything that highlights the crucial parts. It carries labels to make the concept understandable.
• Hence, most of the phenomena that are difficult to observe directly can be handled by making diagrams.
• However, this is not always the case. Modelling can also be done using graphs to visually present data, presentations to enhance concept clarity, etc.
