9 data science project ideas for beginners

Beginners should undertake data science projects as they provide practical experience and help in the application of theoretical concepts learned in courses, building a portfolio and enhancing skills. This allows them to gain confidence and stand out in the competitive job market.

If you’re considering a data science dissertation project or simply want to showcase proficiency in the field by conducting independent research and applying advanced data analysis techniques, the following project ideas may prove useful.

Sentiment analysis of product reviews

This involves analyzing a data set and creating visualizations to better understand the data. For instance, a project idea may be to examine user evaluations of products on Amazon using natural language processing (NLP) methods to ascertain the general mood toward such things. To accomplish this, a sizable collection of product reviews from Amazon can be gathered by using web scraping methods or an Amazon product API.

In order to comprehend the general opinion of the product, the results might be represented using graphs or other data visualization tools.
