Standard Normal Distribution Plot (Mean = 0, STD = 1) SciPy has a variety of methods that can be used to estimate the best distribution of random variables, as well as parameters that can best simulate this adaptability. Normal Distribution is a probability function used in statistics that tells about how the data values are distributed. NumPy arange() is used to create and return a reference to a uniformly distributed ndarray instance. This displays a table of detailed distribution information for each of the 9 attributes in our data frame. To calculate normal probability density of the data norm.pdf is used, it refers to the normal probability density function which is a module in scipy library that uses the above probability density function to calculate the value. Since the p-value is less than .05, we reject the null hypothesis of the Shapiro-Wilk test. WebW3Schools offers free online tutorials, references and exercises in all the major languages of the web.
