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 quantity r, called the linear correlation coefficient, measures the strength and the direction of a linear relationship between two variables.The linear correlation. coefficient is sometimes referred to as the Pearson product moment correlation coefficient in. honor of its developer Karl Pearson.Positive values indicate a relationship between x and y variables such that as values for x increases, values for y also increase.Negative correlation: If x and y have a strong negative linear correlation, r is close to -1.he linear correlation. coefficient is sometimes referred to as the Pearson product moment correlation coefficient in. honor of its developer Karl Pearson. Positive values indicate a relationship between x and y variables such that as values for x increases, values for y also increase.
