In the late 1930's, Stevens advanced a program for the restructuring of psychology on the basis of operationalism. In 1957, after dozens of experiments on direct scaling, such as magnitude estimation, appeared in the literature, S. S. Stevens proposed a new law to relate sensation magnitude to stimulus intensity: So when plotted on log-log axes, the power law plots as a straight line with a slope of the exponent. The theory is named after psychophysicist Stanley Smith Stevens (1906-1973).

The combination of new technologies and easily accessing data can lead to visually presenting information that makes us think differently about the world around us.Data visualization can also present graphics to better illustrate your research project or paper. So we're going to create 2 visualizations. This approach has been criticized for failing to account for individual differences [2,5], finding, for example, that such laws may not fit as originally described [5] or that variation between individuals complicates straightforward application of the laws in practice [2].
