Editing Scatter plot (section)

== Example ==
For example, to display a link between a person's lung capacity, and how long that person could hold their breath, a researcher would choose a group of people to study, then measure each one's lung capacity (first variable) and how long that person could hold their breath (second variable). The researcher would then plot the data in a scatter plot, assigning "lung capacity" to the horizontal axis, and "time holding breath" to the vertical axis.{{fact|date=April 2024}}

A person with a lung capacity of {{val|400|ul=cl}} who held their breath for {{val|21.7|u=seconds}} would be represented by a single dot on the scatter plot at the point (400, 21.7) in the [[Cartesian coordinate system|Cartesian coordinates]]. The scatter plot of all the people in the study would enable the researcher to obtain a visual comparison of the two variables in the data set and will help to determine what kind of relationship there might be between the two variables.{{fact|date=April 2024}}
