“How can I showcase my data skills to the world?” you may be asking. Fear not, for the solution lies in assembling a sparkling portfolio of data science projects!

A fantastic portfolio is more than simply a showcase of your abilities; it’s your golden ticket to the data-driven paradise or Job where chances abound at every angle. You will be given a treasure trove of the top data science portfolio projects that will have you saying, “Whoa, I can do that too!”

In this Article, All mentioned projects will be your resume or portfolio projects from beginner to advanced level. Along with this, three will be dataset sources and also, how you will approach that project to accomplish and add it to your portfolio.

So, whether you are a novice or a skilled professional working in data science, these projects can take you from a good data scientist to a seasoned pro. Without any wait, let’s get started.

Here is a list of data science portfolio projects from beginner to advanced:

## **Beginner Portfolio Projects for Data Scientists**

### **Exploratory Data Analysis (EDA)**:

**Methodology:** Analyse and find significant insights from a public dataset of your choice. You are free to use whichever programming language but Python is recommended or the data visualisation tool you like. You might, for example, use Airbnb information to discover the most popular cities and neighbourhoods, as well as the most profitable rental units.

## **Intermediate Portfolio Projects for Data Scientists**

### **Machine learning classification:**

**Methodology:** Train a machine learning model to categorise data into distinct groups. For example, you may train a model using Scikit-Learn to determine if emails are spam or not, or whether photographs contain cats or dogs.

### **Machine learning regression:**

**Methodology:** To forecast a continuous value, train a machine learning model. For example, you might train a model to predict secondary school student performance using Regression or the number of people who would visit a business on a particular day.

**Resources for Student Performance Prediction**

* Dataset: [Student Performance](https://archive.ics.uci.edu/dataset/320/student+performance)

* [Pandas Documentation](https://pandas.pydata.org/docs/)

### **Machine Learning Clustering:**

**Methodology:** Machine learning is often used to find groupings of similar data points. Customers, for example, may be clustered based on their purchasing history, or items could be clustered based on their attributes.

**Resources for Retail Purchasing**

* Dataset: [Online Retail Data](https://archive.ics.uci.edu/dataset/502/online+retail+ii)

* [Scikit-Learn Clustering](https://scikit-learn.org/stable/modules/clustering.html)

## **Final thoughts**

When choosing a project, it is important to consider your skills and experience level. You should also choose a project that you are interested in and that you are motivated to complete. Therefore, you are free to find some other datasets for your desired field or interest.

Here are some additional tips for creating a strong data science portfolio:

* **Focus on the impact of your work.** What problem did you solve? How did your work benefit the users or the business?

* **Document your process.** Include a brief description of your project, the data you used, the methods you used, and the results you obtained.

* **Publish your code.** This will allow potential employers to see your coding skills and how you approach data science problems.

* **Present your work clearly and concisely.** Use data visualizations and other storytelling techniques to communicate your findings to a non-technical audience.

By following these tips, you can create a data science portfolio that will showcase your skills and experience, and help you land your dream job.

Hurrah, You read it all.
