Mar 3, 2024 · The quantile-quantile (q-q) plot is a graphical technique for determining if two data sets come from populations with a common distribution. A q-q plot is a plot of the quantiles of the first data set against the quantiles of the second data set. By a quantile, we mean the fraction (or percent) of points below the given value. Q-Q plot is often called quantile plot. It is a 2D plot in which we compare the theoretical quantiles of a distribution with the sample quantiles of a dataset. If the dataset has been generated from that distribution, we expect this chart to be close to a 45-degree line, because the sample quantiles will be similar to the theoretical quantiles.A Q-Q plot is a type of plot that we can use to determine whether or not a set of data potentially came from some theoretical distribution.
