In an era dominated by large volumes of data, the ability to mine crucial information and make informed decisions is a vital skill set that shouldn't be undermined. In data science, curiosity meets computation, and raw data is transformed into actionable insights to predict the future, save lives, and change how businesses operate. 
According to data provided by the [United States Bureau of Labor Statistics](https://www.bls.gov/ooh/math/data-scientists.htm#tab-6), data scientist jobs are forecasted to grow by 36 percent between 2021 and 2031. Additionally, for various companies to maintain their competitive advantage and remain in business, they must incorporate the skill sets of a data scientist. This article provides comprehensive details on what you need to know before delving into the world of data science. 

## **Understand your career path**
Data science is wide and cumbersome to understand all the major concepts. Henceforth, to make the learning journey less tedious it is important to set achievable milestones. Data science has various career opportunities which include; 
•	**Data analyst**- focuses on collecting, cleaning, and analyzing data to generate precise decisions. 
•	**Data scientist**- involves creating predictive models and building data-driven solutions to complex problems. 
•	**Data engineer**- mainly entails building and maintaining the infrastructure and architecture needed for data generation, storage, and retrieval. 
•	**NLP engineer**- a Natural Language Processing (NLP) engineer works on comprehending, processing, and analyzing human language. 
•	**BI analyst**- focuses on creating reports, dashboards, and visualizations to help organizations understand and make data-driven decisions. 
•	**Machine learning engineering**- involves researching, building, and designing machine learning algorithms and models.

## **Steps to becoming a data science guru** 
A proficient data scientist requires multiple skills that cut across different areas such as mathematics, programming, communication, and curiosity.
	**1. Learn basics mathematics fundamentals**
Data scientists work with huge volumes of data; therefore, to effectively derive insightful information from the data, they need to have a strong foundation in mathematics. Begin with the basics of mathematics, including calculus, statistics, and probability.
	**2. Programming language** 
Programming is an essential block in data science, they enable data scientists to perform various tasks like data analysis, data visualization, and machine learning. There are several programming languages used in data science and the choice depends on personal preference and the task undertaken. However, the most common programming languages in data science include; 
**a)	Python**- known for its simplicity, readability, and enormous ecosystem of libraries and frameworks, it is the most used [programming language](https://www.datacamp.com/courses/intro-to-python-for-data-science) among data scientists. Some of the key Python libraries used in data science include; Pandas, Matplotlib, NumPy, Seaborn, and TensorFlow. 
**b)	SQL**- Structured Query Language is vital for managing and querying databases. Furthermore, it is crucial for data retrieval and data cleaning. 
**c)	R**- it is mainly designed for statistical analysis and data visualization. Additionally, it is famous for statistical modeling, making it a preferred language for data analysts and statisticians. Some common packages in R programming include; tidyverse, which has ggplot2 and dplyr. 
   **3. Effective communication** 
Clear and effective communication is a vital aspect of any successful relationship, be it personal or professional. It involves exchanging ideas, information, and thoughts between individuals or groups to ensure that everyone is on the same page. Good communication skills can help in improving productivity, building strong bonds, and avoiding misunderstandings. 
In data science, after completing all the essential tasks, you need to interpret your findings to the organization. Therefore, effective communication skills are crucial for a data scientist. At this stage, you must master the key values of communication to convey your findings accurately and efficiently.
**a.	Visualization**- this enables you to pass your findings by creating charts, graphs, and dashboards that enable non-technical users to comprehend easily and quickly. In Python programming, you can use libraries like Matplotlib and [Seaborn](https://www.datacamp.com/courses/introduction-to-data-visualization-with-seaborn) for data visualization. Ensure to always label axes, provide legends, and write clear, concise titles.
**b.	Documentation**- always generate clear and well-structured reports to share your results. Furthermore, use simple language, provide context, and ensure that you provide a detailed summary at the beginning of reports. 
**c.	Storytelling**- master the art of weaving your findings into a compelling narrative. When presenting your results aim at incorporating real-life scenarios. Explain the problem, your approach, key findings, and the implications for decision-making.
**4. Curiosity** 
Curiosity is what drives data scientists to dig deeper into data, find solutions, and make significant decisions. Moreover, it is a trait that compliments the technical skills and knowledge needed for a successful data scientist. So how does curiosity play a role in data science?
**a. Asking the right questions**- proficient data scientists constantly ask questions to understand why certain patterns occur, what factors influence specific results, and how the data can solve current real-world problems. 
**b. Exploring data**- it is a fundamental part of data science that drives data scientists to dive into datasets, examine variables, and unearth hidden trends. 

## Conclusion 
Whether you aspire to be a data analyst, data scientist, machine learning engineer, or just desire a deeper understanding of the data-driven world, this roadmap is your gateway to success. However, it is vital to note that the secret to becoming a data guru is through consistency, practice, and persistence. Additionally, aim to work on projects that involve real-world problems to practice what you learned.
