Data Scientist Vs Data Analyst: Key Differences, Career Paths, and How to Choose the Right Role

The world is becoming increasingly reliant on data, about 2.5 quintillion bytes of data are generated every day and that’s a great sign for anyone interested in a data-driven career. There are many career paths related to data including data scientist, data analyst, ML engineer, AI engineer, BI engineer, and many more. This blog focuses on understanding the difference between a data scientist vs data analyst. Both fields have great potential to grow and are highly in demand. Let’s explore these fields with WeCloudData!

What is a Data Scientist?

In the data world, the best way to define a data scientist is  “jack of all trades”. They work on the entire data pipeline with the primary focus on extracting meaningful insights from the data. From data collection and cleaning to data analysis, visualization, building predictive models, and sharing results with stakeholders, a data scientist wears many hats. They use data mining, statistical methods, predictive analytics, and machine learning to get actionable insights from raw data. Data scientists work in industries ranging from sports to healthcare and finance. To learn more about Data Science follow this link.

What Does A Data Scientist Do?

The role and responsibilities of a Data Scientist are given below;

• Data Collection and Cleaning: A data project starts from gathering raw data from multiple sources. Data scientists clean that raw data and prepare it for further analysis.
• Exploratory Data Analysis (EDA): Data Scientists perform exploratory analysis to understand the data structure, trends, and patterns.
• Statistical Analysis and Predictive Modeling: Data scientists use statistical methods along with predictive modeling. They build and validate predictive models using statistical techniques and ML algorithms.
• Data Visualization and Reporting: Data visualization and communicating the insights to the shareholder is the last activity in the data project lifecycle.

Skill Required for Data Scientist

Skills set for data scientist include:

• Programming languages: Python (basic to advanced), R, and SQL are programming languages used by data scientists.
• Tools for Data Analysis: Matplotlib, Seaborn, NumPy, and Pandas.
• ML Frameworks: TensorFlow, PyTorch, and Scikit-learn are machine learning frameworks data scientists use.
• Statistical knowledge: Regression analysis, probability, and hypothesis testing are examples of statistical knowledge.
• Data visualization tools: Data visualization tools include Tableau and PowerBI.
• Soft skills:  Soft skills include problem-solving, narrative, and communication.

What is a Data Analyst?

The data analyst role is more focused on providing insights from data by making reports and visual ads that give meaningful information to stakeholders. The primary goal of a data Analyst is to analyze data to assist organizations in making informed data-driven decisions. While their work is less technical than that of a data scientist, their contributions to business strategy development are highly required.

What Does A Data Analyst Do?

The role and responsibilities of a Data Analyst are given below;

Data Collection and Cleaning: Data Analyst collects data from multiple sources and cleans it to remove inconsistencies. They mostly use structured data and organize data into usable formats.

Data Exploration and Analysis: Data analysts perform data exploration and analysis to find hidden patterns and insights from data. They do descriptive analytics, and data segmentation and use statistical techniques to identify correlation in data.

Data Visualization: Data analysts are good at data visualization. They present data in the form of graphs and charts that are easy to understand by stakeholders.  Data analysts create interactive reports using tools like Tableau, PowerBI, and Excel that allow stakeholders to explore data on their own.

Reporting and Communication:  Data analysts act as a bridge between technical teams and business stakeholders by translating data into actionable insights.

Skill Required For Data Analyst

Skills set for data Analyst include:

• Data Analysis tools: Proficiency in Data Analysis tools include Tableau and PowerBI.
• SQL: Ability to write complex queries and work with relational databases using SQL.
• Basic Statistics: Understanding of basic statistical concepts like mean, median, standard deviation, and correlation.
• Programming (Optional): Familiarity with Python for advanced analysis.
• Problem-Solving: Analytical mindset to solve business problems using data.
• Time Management: Ability to prioritize tasks and meet deadlines.
• Communication: Must be good at storytelling to present insights effectively.
• Attention to Detail: Strong ability to find inconsistencies in data.

How to Choose Between Data Scientist and Data Analyst Roles

Choosing between a career as a data scientist and a data analyst depends on your interests, skills, and career goals.

1. Interests

Consider pursuing a career in data science if you like coding, machine learning, and solving challenging issues.While a career  as a data analyst might be more suitable for you if you enjoy working with data visualization tools and producing reports and are good at communication.

2. Skills

• Data Scientists: Require strong programming and mathematical skills.
• Data Analysts: Require proficiency in SQL and data visualization tools.

3. Career Goals

• Aim for a position as a data scientist if you want to work with cutting-edge technologies and predictive modeling.
• If you want to start with a less technical role and potentially plan to transition towards data science,and then to ML engineer start as a data analyst.
