There are many purposes for graphs and tables in science. They can be used to communicate data, to visualize trends, or to make comparisons.
Graphs and tables can be used to communicate data by displaying different aspects of the data in an easy-to-understand way. For example, a table can show the different values of a variable, while a graph can illustrate how those values change over time.
Trends can be visualized using graphs and tables. For example, a graph can show how a particular variable changes over time, while a table can compare the values of that variable across different groups.
Comparisons can be made using graphs and tables. For example, a graph can compare the values of a variable across different groups, while a table can show how those values change over time.
