WebMar 24, 2015 · Laura LeBlanc, 1204502. As defined by Venes & Taber (2005), “linearity in radiography is the production of a constant amount of radiation for different combinations of milliamperage and exposure time”. In the clinical setting, it is essential that all general x-ray units produce a proportional change in exposure as milliamperage (mA) varies. WebFor example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables. It is important to note that there may be a non-linear association between two ...
