Information Analysis Projects for Beginners

Projects are an excellent way to gain feel with the end-to-cease data analysis process, particularly if you're new to the field of information analysis. Here are some great projection ideas for beginners:

Web Scraping

Spider web scraping is the extraction of information—such as images, user reviews, or product descriptions—from web pages. This information is first collected, then formatted. Web scraping tin be done past writing custom scripts in Python, or by using an API or web scraping tool such as ParseHub. Hither are two pop means to practice web scraping:

Reddit is a popular repository for spider web scraping considering of the sheer corporeality of data available— from qualitative information in posts and comments to user metadata and engagement with each postal service.

Subreddits on Twitter enable you to extract posts on specific topics. PRAW is a Python package you can use to access Reddit'due south API to scrape the subreddits you lot're interested in (a Reddit business relationship is required to become an API key). You lot can then excerpt data from one or more subreddits at a time. If you'd rather not scrape your own data, you can find Reddit datasets on data.world.

Real Estate

If y'all're interested in real manor, you can utilise Python to scrape data on existent-estate properties, then create a dashboard to clarify the "best" properties based on data points like property taxes, population, schools, and public transportation. There are 2 primary Python libraries for data scraping: Scrapy and BeautifulSoup. You tin can likewise use the Zillow API to obtain real estate and mortgage data.

Exploratory Data Analysis

Another groovy project for beginners is to exercise an exploratory data analysis (EDA), which is the probing of a dataset to summarize its main characteristics. EDA helps determine which statistical techniques are appropriate for a given dataset. Here are some projects where you lot tin can piece of work on your EDA chops:

McDonald'south Diet Facts

McDonald's food items are often controversial because of their high fat and sodium content. Using this dataset from Kaggle, you tin can perform a nutrition analysis of every menu item, including salads, beverages, and desserts. First, import the CSV file in Python. And so, categorize items co-ordinate to factors like sugar and fiber content. Then you can model the results using bar and pie charts, besprinkle plots, and heatmaps. For this project, you'll need the Numpy, Pandas, and Seaborn libraries.
