On the Probability Paper
Full text linkThe probability paper (PP) is a kind of graph paper with an inhomogeneous scale, to which outputs of the cumulative distribution of a given statistical data set are plotted. If the data set obeys normal distribution, the plotted points should be aligned, usually with some fluctuations, enabling us to estimate the mean and standard deviation of the data set. Various aspects of PP are discussed from the standpoint of education. The theory behind PP is explained in terms of continuous distribution and it is shown that the inverse transformation of the cumulative distribution, f–1, plays an essential role for producing alignment. PP effectively applies f–1 to the cumulative distribution of the original data set. Two types of f–1 are examined, one for infinite range and the other for finite range. The former function, singular at end points, explains why PP is usually scaled from 1% to 99%. Monte-Carlo simulations are carried out for some 102 data points. It is described how to produce PP sheets and/or PP-based plots using the computer so that PP may be an interesting material for the students of science or engineering major. Python code is listed for drawing tic marks.departmental bulletin pape
