The points represented in a Q-Q diagram are not always decreasing when viewed from left to right. If the two comparative distributions are identical, the Q-Q diagram follows the line y = x at 45°. If the two distributions match in one of the distributions after linear transformation of the values, the Q-Q diagram follows a line, but not necessarily the line y = x. If the general trend of the Q-Q diagram is flatter than the line y = x, the distribution represented on the horizontal axis is more distributed than the distribution represented on the vertical axis. Conversely, if the general trend of the Q-Q diagram is steeper than the line y = x, the distribution drawn on the vertical axis is more distributed than the distribution drawn on the horizontal axis. Q-Q diagrams are often curved or “S”, indicating that one of the distributions is more inclined than the other or that one of the distributions has heavier tails than the other. The term “probability diagram” sometimes refers specifically to a Q-Q diagram, sometimes to a more general class of diagrams, and sometimes to the less used P-P chart. The correlation coefficient diagram probability diagram (PPCC diagram) is a size derived from the idea of Q-Q diagrams, which measures the concordance of an adapted distribution with the observed data and is sometimes used as a means of adjusting a data distribution. The choice of quantiles from a theoretical distribution may depend on the context and purpose. A choice given to a sample of size n is k/n for k = 1, …, n, because it is the quantiles that carry out the distribution of the sample. The last, n/n, corresponds to the percentenile – the maximum value of the theoretical distribution, which is sometimes infinite.

Other possibilities are the use of (k ? 0.5) / n or rather the uniformity of points in the equal distribution with k / (n + 1). In other words, with a probability, we want the corresponding quantil of the cumulative distribution function. The medians of the order statistics are the medians of the order statistics of the distribution. These can be expressed with regard to the quantil function and the medians of order statistics for a continuous regular distribution: many other options have been proposed, both formal and heuristic, on the basis of theories or simulations relevant to the context. Some of these are explained in the following subsections. A narrower question is the choice of a maximum (estimation of a maximum population), known as the German reservoir problem, for which there are similar solutions “maximum sample plus a deviation”, the simplest m + m / n – 1. A more formal application of this standardization of distance is carried out in the estimation of the maximum distance of the parameters. More generally, the Shapiro-Wilk test uses the expected values of the order statistics of the given distribution; The resulting diagram and line give the general estimate of the smallest squares for position and scale (of the intersection and slope of the adjusted line).  While this is not too large for the normal distribution (location and scale are estimated by mean or standard deviation), it can be useful for many other distributions. . . .
