A scatterplot or scatter graph is a graph used in statistics to visually display and compare two or more sets of related quantitative, or numerical, data by displaying only finitely many points, each having a coordinate on a horizontal and a vertical axis. A graph of a bell curve in a normal distribution showing statistics used in educational assessment, comparing various grading methods. ... A coordinate axis is one of a set of vectors that defines a coordinate system. ...

Part of Seven tools of quality (Quality improvement tools that include the histogram, Pareto chart, check sheet, control chart, cause-and-effect diagram, flowchart, and scatter diagram.) see [[1]] The control chart, also known as the Shewhart chart or process-behaviour chart is a statistical tool intended to assess the nature of variation in a process and to facilitate forecasting and management. ... A simple flowchart for what to do if a lamp doesnt work A flowchart (also spelled flow-chart and flow chart) is a schematic representation of a process. ...

For example, if a statistician were studying the effects of lung capacity on the ability to hold one's breath, he would choose a group of people to study, and he would test each one's lung capacity (first data set) and how long that person could hold their breath (second data set). Then he would set up a scatter plot, assigning "lung capacity" to the horizontal axis, and "time holding breath" to the vertical axis. A person with a lung capacity of 400 cc who held their breath for 21.7 seconds would be represented by a single dot on the scatter plot at the point (400, 21.7) in Cartesian coordinates. The scatter plot of all the people in the study would enable the statistician to obtain a visual comparison of the two sets of data, and help him to determine what kind of relationship there might be between them. The lungs flank the heart and great vessels in the chest cavity. ... Cartesian means relating to the French mathematician and philosopher Descartes, who, among other things, worked to merge algebra and Euclidean geometry. ...

Scatter Plot (or scatter diagram) shows the position of all of the cases in an x-y or x-y-z coordinate system. The relationship between interval variables can be identified from scatter graph.

• The independent variable is plotted on the x-axis, or the horizontal axis.
• The dependent variable is plotted on the y-axis, or the vertical axis.

A dot in the body of the chart represents the intersection of the data on the x and y axis
