Observations and Data: Types of Graphs

The video tutorial explains different types of graphs: line graphs, bar graphs, and circle graphs. Line graphs are useful for showing changes over time, such as population growth or temperature variations. Bar graphs represent data using bars, with double bar graphs allowing for comparison between two data sets. Circle graphs, or pie charts, show how data groups relate to the whole, often expressed in percentages. Each graph type is illustrated with examples to demonstrate their practical applications.
