Overview of this book

With the SciPy Stack, you get the power to effectively process, manipulate, and visualize your data using the popular Python language. Utilizing SciPy correctly can sometimes be a very tricky proposition. This book provides the right techniques so you can use SciPy to perform different data science tasks with ease. This book includes hands-on recipes for using the different components of the SciPy Stack such as NumPy, SciPy, matplotlib, and pandas, among others. You will use these libraries to solve real-world problems in linear algebra, numerical analysis, data visualization, and much more. The recipes included in the book will ensure you get a practical understanding not only of how a particular feature in SciPy Stack works, but also of its application to real-world problems. The independent nature of the recipes also ensure that you can pick up any one and learn about a particular feature of SciPy without reading through the other recipes, thus making the book a very handy and useful guide.

Computing the summary statistics of a dataset

Obtaining the summary statistics of a dataset helps us to understand quite a few attributes of the dataset:

  • Number of observations in the dataset
  • Minimum value and maximum value
  • Variance of the dataset
  • Mean values in the dataset
  • Skewness of the dataset
  • Kurtosis of the dataset

How to do it...

The summary statistics of a dataset can be obtained using the describe function within scipy.stats.

The process to obtain the summary statistics of a dataset is as follows:

  1. Import the relevant packages:
from scipy import stats
  1. Initialize an array:
a = np.arange(10)

In the preceding code, we have initialized a one-dimensional array.

  1. Fetch the summary statistics of the dataset (array)...
