Checking the quartiles of a dataset

The quartile is like the percentile because it can be used to measure the spread and identify the center of a dataset. Percentiles and quartiles are called quantiles. While the percentile divides the dataset into 100 equal portions, the quartile divides the dataset into 4 equal portions. Typically, three quartiles will split your dataset into four equal portions.

To analyze the quartiles of a dataset, we will use the quantiles method from the numpy library in Python. Unlike percentile, the quartile doesn’t have a specific method dedicated to it.

Getting ready

We will work with the COVID-19 cases again for this recipe.

How to do it…

We will compute the quartiles using the numpy library:

1. Import the numpy and pandas libraries:

   import numpy as np
   import pandas as pd

2. Load the .csv into a dataframe using read_csv. Then subset the dataframe to include only relevant columns:

   covid_data = pd.read_csv("covid-data...
