Linear regression

This scatter graph (scattergraph. scatter chart, scatter plot, scatterplot, scatter diagram) sample shows that a linear relationship between the two variables indicating that a linear regression model might be appropriate. It was designed on the base of data from the Engineering Statistics Handbook on the website of the National Institute of Standards and Technology (NIST), the U.S. Department of Commerce. [itl.nist.gov/div898/handbook/eda/section3/eda33q.htm] "In statistics, linear regression is an approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables (or independent variables) denoted X. The case of one explanatory variable is called simple linear regression." [Linear regression. Wikipedia] The scatter chart example "Linear regression" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Scatter Diagrams solution from the Graphs and Charts area of ConceptDraw Solution Park.
