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 Purpose of Correlational Research. Correlational studies are used to look for relationships between variables. There are three possible results of a correlational study: a positive correlation, a negative correlation, and no correlation. The correlation coefficient is a measure of correlation strength and can range from â1.00 to +1.00. Positive Correlations: In this type of correlation, both variables increase or decrease at the same time. A correlation coefficient close to +1.00 indicates a strong positive correlation.
