Here, loc parameter is also known as the mean and the scale parameter is also known as standard deviation. If you actually want to see "how many have the same count", rather than a representation of the disribution, then you'll either need to set the bins kwarg to be df["count"].max()-df["count"].min() - or do as you said and count the number of times you get each count and then create a bar chart. The following code shows how to create a histogram for a dataset that follows a log-normal distribution: By simply looking at this histogram, we can tell the dataset does not exhibit a bell-shape and is not normally distributed. Also no idea where you came up with 100 and 110 in min and max args for b. I think you are using the wrong numpy function: np.random.randint returns random integers from the discrete uniform distribution. Infos Utiles If you want a random normal distribution, you need to use np.random.normal, namely: where loc corresponds to the mean value, and scale to the standard deviation value of the distribution. 1. To get the the description about your distribution you can use: df ['NS'].value_counts ().describe () To plot the distribution: import matplotlib.pyplot as plt 2. Many statistical functions require that a distribution be normal or nearly normal. For example, for the data in this problem, the mean and standard deviation of the best-fitting normal distribution can be found as follows: The function xlim() within the Pyplot module of the Matplotlib library is used to obtain or set the x limit of this axis. The probability density function of normal or Gaussian distribution is given by: Where, x is the variable, mu is the mean, and sigma standard deviation. 3.3.
