Numerical data refers to information that is expressed in numbers. It can be collected through measurements, observations, or calculations.
Think of numerical data as a recipe for a cake. Just like a recipe provides specific quantities of ingredients, numerical data provides specific values for different variables.
Mathematical Equations: Mathematical equations are expressions that use mathematical symbols and operations to represent relationships between variables.
Diagrammatic Representations: Diagrammatic representations are visual tools such as graphs, charts, or diagrams that help illustrate and analyze numerical data.
Experimental Data: Experimental data refers to numerical information obtained through scientific experiments or investigations.
