Histogram bell shaped
Webb15 jan. 2024 · My code so far, I'm very new to programming and have been trying for a while. Here I apply the Box-Muller transform to approximate two Gaussian normal distributions starting from a random uniform sampling. Then, I create a histogram for both of them. Now, I would like to compare the obtained histograms with "the real thing": a … WebbBell-Shaped is a histogram with a prominent’mound’ in the center, as well as similar tapering to the left and right. The data is unimodal, which means it has a single mode identified by the ‘peak’ of the curve, which is one indication of this shape.
