Module 2â Unit 2 Industrial Insulation Phase 2 2 Orthographic Projections Revision 2.0, August 2014 Introduction Orthographic projection is a means of representing a three dimensional object on a plane surface.Two principal planes are used in orthographic projection, one horizonta l and one vertical.odule 2â Unit 2 Industrial Insulation Phase 2 15 Orthographic Projections Revision 2.0, August 2014 2.4 Dimensioning The addition of sizes and measurements to a drawing is known as âdimensioningâ. Dimensions tell us the exact distance between two points of surfaces, therefore it is essential that they are legible.
The value of a correlation coefficient ranges between -1 and 1. The greater the absolute value of a correlation coefficient, the stronger the linear relationship. The strongest linear relationship is indicated by a correlation coefficient of -1 or 1. The weakest linear relationship is indicated by a correlation coefficient equal to 0.
The linear correlation coefficient measures the relationship between the paired values in a sample. Sum up the values of the first column of data (). Simplify the expression. Sum up the values of the second column of data ().
