Being that DataScience is very high in demand, the questions and curiosity around it also rises. Data science is still evolving and a mystery to some as we enter 2024, the aim of this article is providing a wide range of information for newcomers to study and succeed in this field. This roadmap should walk you through the stages and tools you need to get your career in data science off to a really good start, whether you're a novice or someone wishing to change careers.

Describing data science.
Data science is an interdisciplinary field that uses methods from computer science, statistics, and expertise to draw important conclusions and information from data. These data are then used by experts to make well-informed decisions, solve challenges or issues that arise in real world situations, and forecast future situations.

The Roadmap Direction:

1. Gain an Understanding of Programming Languages: Python or R are two popular programming languages used in data science. Online Courses: Sites like Coursera, Udemy, and Codecademy, e.t.c provide some of the best beginner programming courses.
2. You need to recognize mathematics and statistics Learn basic ideas in probability and statistics, like distributions and statistical tests. Calculus and linear algebra are the basics that are required to comprehend machine learning algorithms. Online Courses: Comprehensive tutorials sites like Khan Academy.
3. Train yourself on Data Analysis and Manipulation Manipulation and analysis of data with Python's Pandas package. Data Visualization: Get familiar with programs like Matplotlib and Seaborn for data visualization( Tip: Seaborn is more visually appealing). Use tutorials, blogs, and YouTube channels.
4. Machine Learning Most importantly, supervised and unsupervised learning algorithms for machine learning. Then, Python machine learning library Scikit-Learn. You can register in machine learning classes on websites like Coursera e.g Andrew Ng's Machine Learning course
5. Deeper Machine Learning Levels Here we have convolutional neural networks (CNNs) and recurrent neural networks (RNNs), as well as deep learning frameworks like TensorFlow and PyTorch. Online Courses: Coursera - Deep Learning Specialization.
6. Real-World Knowledge You can also join in real-world projects and data science competitions on Kaggle like the titanic data set. Also, work on personal projects like data analysis, forecasting models, or a website portfolio to display all your work for people to see.

Tools for Data Science;
Big Data: Instruments like Hadoop for enormous datasets in regards to big data.

Database management: Get to know databases used for data storage, for example SQL and NoSQL.

Data Science Libraries:
Numpy is very crucial to perform numerical computations.
For more complex scientific and technical computing, study SciPy library.

1. More Advanced Aspects: Topics like natural language processing (NLP) for sentiment analysis and text analysis. Also research on using computer vision to identify objects and recognize images and then time series data for forecasting by performing a time series analysis.
2. Soft skills Problem-Solving: Develop your ability to solve problems to meet obstacles in the actual world. Communication: To communicate complex results from your work as a data scientist, develop good communication skills.

Various Tools and Learning Environments
Platforms like Coursera, edX, Udacity, and DataCamp have large and properly broken down data science courses and aspects of specializations.
YouTube: StatQuest with Josh Starmer, Corey Schafer, and Data School all provide helpful tutorials.
Community: Connect with friends and experts similar to your field by joining data science communities on websites like Stack Overflow, and LinkedIn.
At some point, you will need to build a Data Science Portfolio as you advance in learning and gaining more knowledge, A portfolio is important to showcase your knowledge and skill as well as abilities to potential employers. A neat portfolio can make a good impression on potential employers and show your professionalism.
As soon as one is happy with the knowledge gained so far in data science abilities, it is time to network and look for job opportunities:

You can attend data science webinars, and meetups to network with industry experts.

Update your LinkedIn profile to be up to date with all your progress so far as well as educational background even for people transitioning career.
Finally, start submitting your resume for internships, entry-level opportunities, or junior roles in data science or related industries like BI Analysts or data analysts.
Practice frequently in data science for interviews as practice makes you better!

Data Science: Constantly Evolving!
Always remember that learning is continual and data science is a field that is constantly changing so you have to keep up. It is important to stay current with market trends, and learn to use new tools as they become available. Accept challenges too and be happy with the process in general. A positive attitude will help for sure.
