The diagram can be prolonged on your desire with statistical data according to further baby's growth.Įxample 2: Scatter Plot - Linear Regression At this, if from 0 to 18 months we can see the active growth, from 18 to 24 months the child's height is almost stable and unaltered. When looking at this diagram, you can note that the newborn has a height near 56 cm, when the child at the age of two years is little more than 80 cm. Each of them has the value of one variable determining the position on the horizontal axis and the value of the other variable determining its position on the vertical axis. Any scatter diagram displays data as a collection of points, you can see well visible large red points in this sample that depict the statistical dependence, how the baby’s height relates to its age. This informative sample visualizes the correlation between a baby's height and age. An experienced user spent 5 minutes creating this sample. This example was created in ConceptDraw DIAGRAM using the Scatter Diagrams library from the Scatter Diagrams solution. Use the ConceptDraw DIAGRAM application's ability to enter the data to the table and to construct the Scatter Plot Graph automatically according to these data. The Scatter Chart Solution makes it easy to design attractive Scatter Diagrams used in various fields of science, work, and life activities. The Scatter Diagrams Solution extends ConceptDraw DIAGRAM functionality with templates, samples, and a library of vector stencils that make simple the construction of a Scatter Plot of any complexity. However, in some cases, a strong relationship can also be significantly affected by some third variable, which eventually clusters the points on the Scatter Diagram. The more this cluster is similar to the straight line, the stronger is the correlation between the paired data. The direction and compactness of the points' cluster indicate the type and strength of the relationship between two variables, on the basis of which it is possible to make certain conclusions and to take further decisions. The correlation can be positive, negative, or null, and its type can be easily determined with only a glance at the position of points on the Scatter Chart.Ī Scatter Chart is a quite informative diagram. Scatter Diagrams are used for identifying potential linear and nonlinear relationships between variables, as well as to show the absence or presence of correlation between two variables and to define its degree, to depict the relationships of price and quality rating, to determine the correlation between the quality parameter and the factor affecting it. A Scatter Chart displays the data set as a collection of points in Cartesian coordinates each of them is determined by the values of two variables (position on the horizontal axis and vertical axis). This is a simple and convenient tool intended to identify the relationship between two types of data and allowing one to visualize how a change in one variable affects another one. A Scatter Chart (other names Scatter Plot, Scatter Diagram, Scatter Graph, Correlation Chart) is one of the Seven Basic tools of quality control.
