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.

What is a line graph and what are its advantages?

How can we represent the data from the melting and boiling of water experiment in a bar graph?

What is a double bar graph and how does it differ from a regular bar graph?

Explain the purpose of a circle graph and how it represents data.

In what ways can a circle graph be used to represent different types of data?
