# Ordered Numerical Data

Learn how to handle and retrieve information from ordered sequences of numerical data.

## We'll cover the following

## Introduction

When handling numerical features, one of the intuitive things we’ll do is to get a sense of the ordered sequence of the numbers. Beyond the basic `sort_values()`

and `sort_index()`

that we’re already familiar with, we can retrieve information from sorted arrays with the methods of `nlargest()`

, `nsmallest()`

, and `rank()`

. We’ll use a subset of the credit card dataset to illustrate these `pandas`

methods.
