How to Read Data Tables - When students are introduced to the concept of graphing, they come across data tables. These tables have a high significance in not only mathematics but also daily lives. In order to learn graphing skills, students need to have a clear understanding of what data tables are and how to read them. Data tables comprise of two quantities: an independent quantity and a dependent quantity. These display the corresponding values of two variables. The tables can be read from left to right or from top to bottom. When you read a table down a column or across a row, it can help you create a graph.
