to Identify the measurements to be taken, they should be variables and they both should be able to be measured at the same time (the measurements should be as specific as possible to reduce variation and increase the chance of higher correlation). The third part is to make 50 to 100 pairs of the measurement, ensure that the measurements are as steady as possible so as they do not interfere with the final figures. The next step will be to plot the measured pairs on a scatter Diagram, plot them to give maximum visual spread points; this may involve using different scales and making the axes cross at non-zero value. The last step is that the diagram will be seen and it should be interpreted and action taken accordingly

Sketch graphs of shear force and bending moment distribution and validation of calculations by alternative checking methods, plus analysis of safety factor for a chosen material, incorporating referenced additional data, are required for M/D criteria.

The strength of a correlation is determined in various statistical angles. It is in this aspect that this Correlation, which is represented by the value that fall between, values of -1.00 to +1.00. If the value is 1 positive or negative it means it is a perfect correlation, this rarely occurs as it means that when the variables both change with the same magnitude, while a correlation of 0 means that there is no relationship between the two variables. A correlation of .8, .9 or even .7 is a strong correlation and it means that there is a great relationship between the scores of one variables and the other, while a correlation of .2 or .3 is a weak correlation meaning that there are some relationships between two variables a but it is a weak one.
