## COMPLETE GUIDE TO BECOMING A DATA SCIENTIST.
##STEP 1. GET FOUNDATIONAL EDUCATION.
Getting a broad overview of data science can help you decide whether this career is a good fit while equipping you with job-ready skills. While many positions still require a degree, that’s beginning to change. You can also develop foundational knowledge in programming languages such as Python or R. Python is highly recommended due to its versatility and extensive libraries. In mathematics and statistics, start with the basis of linear algebra, calculus, and probability theory. Understanding statistics is crucial for data. You can also enhance your resume with a degree in math, computer science, or another related field, and learn what you need through alternative programs, like professional certificate programs, boot camps, or self-study courses.

## STEP 2. BUILD YOUR TECHNICAL SKILLS.
Getting a job in data science typically requires having a set of specific technical skills. Whether you’re learning through a degree program, professional certificate, or on your own, these are some essential skills you’ll likely need to get hired; Statistics, R or Python programming, SQL (Structured Query Language), Data Manipulation to explore libraries like Pandas for data cleaning, transformation, and manipulation. Data Visualizations to master Visualization tools like Matplotlib, Seaborn, or Plotly to communicate insights. Afterwards, choose a specialization area(e.g., finance, healthcare, or e-commerce), gain domain-specific knowledge then dive deeper into advanced topics related to your chosen field e.g. Natural Language Processing(NLP).

##STEP 3. WORK ON PROJECTS WITH REAL WORLD DATA.
The best way to learn how to find value in data is to work with it in real-world settings. Look for degree programs or courses that include hands-on projects using real data sets. You can also find a variety of free public data sets you can use to design your projects. Explore the fundamentals of machine learning, including supervised and unsupervised learning. Begin with simple machine learning algorithms like linear regression and k-means clustering. Use Sci-kit Learn, a popular machine-learning library in Python, to implement these algorithms.

##STEP 4. DEVELOP A PORTFOLIO OF YOUR WORK.
As you play around with data sets on the internet or complete hands-on assignments in your classes, be sure to save your best work for your portfolio. A portfolio demonstrates your skills to hiring managers and can go a long way toward getting the job. As you start to curate work for your portfolio, choose projects that demonstrate your ability to scrape data from different sources, clean and normalize raw data, visualize your findings through graphs, charts, maps, and other visualizations, and draw actionable insights from data.
If you’ve worked on any group projects throughout your learning, consider including one of those as well. This shows that you’re able to work as part of a team. In case you’re not sure what to include in your portfolio (or need some inspiration for project ideas), spend some time browsing through other people’s portfolios to see what they’ve chosen to include.
## Tip: 
Sign up for a GitHub account and start posting your projects and code to the site. It’s an excellent spot to network with a community of data scientists, show off your work, and possibly catch the eye of recruiters.


## STEP 5. PRACTICE PRESENTING YOUR FINDINGS.
It can be easy to focus only on the technical aspects of data science but don’t neglect your communication skills. A significant element of working as a data scientist is presenting your findings to decision-makers and other stakeholders in the company.
As you complete projects for your portfolio, practice presenting your findings. Think about what message you want to convey and what visuals you’ll use to support your message. Practice speaking slowly and making eye contact. Practice in front of the mirror or with your classmates. Try recording yourself as you present so you can watch it back and look for areas to improve.

##STEP 6. GET AN ENTRY-LEVEL DATA SCIENTIST JOB.
After gaining some experience working with data and presenting your findings, it’s time to polish your resume and begin applying for entry-level data scientists jobs. Don’t be afraid to apply for positions you don’t feel 100 percent qualified for. Your skills, portfolio, and enthusiasm for a role can often matter more than if you check every bullet item in the qualifications list.
If you’re still in school, ask your university’s career services office about any internship opportunities. With an internship, you can start gaining real-world experience for your resume and apply what you’re learning on the job.

##STEP 7. CONSIDER CERTIFICATION OR AN ADVANCED DEGREE.
Data Science is a constantly evolving field. Stay updated with the latest trends, tools, and techniques through online courses, blogs, and conferences. Certifications, like the  Certified Analytics Professional (CAP) and [DASCA] Senior Data Scientist (SDS), might help qualify you for more advanced positions at higher pay grades.  

## CONCLUSION.
The journey to becoming a data scientist in 2023–2024 is both exciting and challenging. The roadmap outlined here provides a structured path, but your progress will depend on your commitment and curiosity. Embrace challenges, seek mentorship, and keep exploring the vast and exciting world of data science in 2023 and beyond. Good luck on your data science journey!
