Data representation and interpretation is the process of organizing, displaying, and drawing conclusions from numerical information. In Grade 11, we focus on three main graphical representations: stem-and-leaf diagrams, bar charts (including multiple bar charts and component bar charts), and pie charts. Each representation serves a specific purpose and reveals different features of the data. Data Types Discrete data: Data that can only take specific, separate values (e.g., number of students in a class, shoe sizes). Usually counted. Continuous data: Data that can take any value within a range (e.g., height, weight, time). Usually measured. Stem-and-Leaf Diagram
