Analyzing Biological Data

This presentation explores various techniques for organizing biological data, emphasizing the use of tables and graphs. Key tools include bar graphs, line graphs, and circle (pie) graphs, each serving to represent data effectively and show relationships or patterns. The presentation breaks down the elements of these graph types, explaining how to identify independent and dependent variables. Additionally, it discusses how pie graphs illustrate how parts contribute to a whole, with individual percentages adding up to 100%. This comprehensive approach aids in better data interpretation.
