We will generate random values that mimic a normal distribution and analyze the generated data with statistical functions from the scipy.stats package.
Generate random values from a normal distribution using the
scipy.statspackage:generated = stats.norm.rvs(size=900)
Fit the generated values to a normal distribution. This basically gives the mean and standard deviation of the dataset:
print("Mean", "Std", stats.norm.fit(generated))The mean and standard deviation appear as follows:
Mean Std (0.0071293257063200707, 0.95537708218972528)Skewness tells us how skewed (asymmetric) a probability distribution is (see http://en.wikipedia.org/wiki/Skewness). Perform a skewness test. This test returns two values. The second value is the p-value—the probability that the skewness of the dataset does not correspond to a normal distribution.
