Final answer:
A time series graph, which is a type of line graph, is used to chart and analyze changes in the frequency of behavior over time.
Step-by-step explanation:
The graph used to provide standardized means of charting and analyzing how frequency of behavior changes over time is most commonly known as a time series graph. This type of graph utilizes the format of a line graph, with one axis (typically the x-axis) representing increments of time and the other axis (often the y-axis) representing the frequency of the observed behavior. Each point on the line graph represents data from a specific time point, and the points are connected in chronological order. This method effectively illustrates how variables change over time and can reveal trends or patterns, such as fluctuations in unemployment rates or economic data.
