Add normal distributions

WebJan 27, 2024 · For each histogram, I would like to add a Normal Distribution to each histogram with each species mean and standard deviation. Of course I'm aware that I could compute the group specific mean and SD before embarking on the ggplot command, but I wonder whether there is a smarter/faster way to do this. I have tried: WebNORM.DIST (x, mean, standard_dev ,cumulative) The NORM.DIST function gives the probability that a number falls at or below a given value of a normal distribution. x — The value you want to test. mean — The average value of the distribution. standard_dev — The standard deviation of the distribution.
