Line graphs are used to compare changes over the same period of time for more than one group. They can simplify complex data sets into a highly digestible format and are especially useful when dealing with large data sets. To solve a line graph: Identify the graph's title Find the data range Find the increasing value of the x-axis and the y-axis Name the horizontal line as the x-axis and the vertical line as the y-axis Plot each data point based on the frequencies and time intervals Join each data point Here are some tips for solving data interpretation questions: Calculate...
