Understanding Graphs and Data Interpretation

This video tutorial explains how to use graphs to answer various types of questions. It covers the components of bar and picture graphs, common mistakes in interpreting graphs, and the four main types of questions: reference, one-step, two-step, and whole picture questions. The tutorial emphasizes the importance of understanding graph elements like keys and scales to avoid errors and highlights the need for critical thinking in answering whole picture questions.
