Strong positive linear correlation

This scatter graph (scattergraph. scatter chart, scatter plot, scatterplot, scatter diagram) sample illustrates strong positive linear correlation. 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. "Note in the plot ... how a straight line comfortably fits through the data; hence a linear relationship exists. The scatter about the line is quite small, so there is a strong linear relationship. The slope of the line is positive (small values of X correspond to small values of Y; large values of X correspond to large values of Y), so there is a positive co-relation (that is, a positive correlation) between X and Y." [itl.nist.gov/div898/handbook/eda/section3/scatter2.htm] The scatter chart example "Strong positive linear correlation" 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.
