Normal histogram shape
WebSo the normal distribution only makes sense for histograms. …..Why the Bell Shape? Now let’s try to find out why the normal distribution is bell shaped and what causes the hump in the middle. WebBecause histograms display the shape and spread of distributions, you might think they’re the best type of graph for determining whether your data are normally distributed. However, I’ll show you how histograms can trick you! Normal probability plots are a better choice for this task and they are easy to use.
