Homework #1

                                                                                                   (100 points)

Homework 1 considers a Covid-19 dataset which is published on Github. Please download any document type that you prefer of the dataset from the links which are shown in Figure 1. The dataset is updated daily and

 

Figure 1: The complete dataset links

includes data on confirmed cases, deaths, hospitalizations, testing, and vaccinations as well as other variables of potential interest. The data set has the following basic columns:

•    iso code: Short name of the country

•    continent: The continent where the country exists

•    location: The country name

•    date: The date when the data about various variables are taken.

You are responsible to implement a program which reads the given dataset from the file and computes the data for the following questions. Any programming language that you prefer will be accepted. Putting comments on your functions that you implement is must. Each question must be appended to a file which is called ”output{.csv, .txt}”. The file contains the first 18 questions listed below. The 18th question will be written in this document.

19.      Comment the results based on your observations. Write your opinions about the reasons of increasing infection rates by giving examples from the results. Feel free to explain any situation that you observe.

More observations more opportunities will bring you for the second homework.
