Graph Types and Data Interpretation

Teacher Hannah explains the importance of analyzing and interpreting data in science. The video covers how to organize data using tables and various types of graphs, such as line graphs, scatter plots, bar graphs, and pie charts. It also discusses interpreting data by evaluating it, identifying trends, and drawing conclusions. The video includes examples and challenges for students to apply their learning.
