Line Graphs are visual displays that represent the relationship between two variables. The dependent variable (behavior being measured) is plotted on the y-axis, while the independent variable, typically a time element such as sessions, days, or hours, is plotted on the x-axis.
Example
A behavior analyst uses a line graph to track a student’s daily homework completion over a month. The y-axis shows the number of homework assignments completed each day, and the x-axis shows the days of the month. This graph helps the analyst observe trends and patterns in the student’s behavior over time.
