The overlap in skills and duties between data analysts and scientists means that data analysts may transition into data science roles as they gain more experience. However, there are still some key differences between the two roles.
Key Differences Between Data Analysts and Data Scientists
While data analysts and scientists have some common skills, their roles also have some distinct differences. Here are some of the key ways that the two roles diverge:
Focus Area
Data analysts tend to focus on analyzing existing datasets to uncover insights. Their role centers around business operations – they aim to understand what happened and why. Data scientists utilize predictive modeling and machine learning algorithms to make data-driven predictions. Their focus is more research-oriented as they identify patterns in data to anticipate what could happen next.
Tools and Languages
Data analysts commonly use SQL and spreadsheet programs like Excel to extract, clean and analyze data. Data scientists are more likely to use coding languages like Python and R to build machine learning models and perform robust statistical analysis. Here is a comparison:
| Data Analyst | Data Scientist |
|---|---|
| SQL | Python |
| Excel | R |
| Tableau | TensorFlow |
Statistical Depth
While both use statistics, data scientists use more advanced statistical and mathematical concepts. This includes predictive modeling, algorithms, significance testing, multivariate calculus, linear algebra and more advanced machine learning techniques. Data analysts focus more on summary statistics and data visualization to find patterns.
Technical Skills
Data scientists generally have stronger technical skills – they may even have a PhD in a technical field like statistics, math or computer science. Analysts are more likely to have an educational background in business, communications or related fields. Data scientists need skills to build customized machine learning models while analysts mainly use ready-made analytics tools.
Business Focus
Data analysts are focused on addressing business needs and processes. They extract insights to help marketing, operations, finance teams make better decisions. Data scientists have a stronger research focus – they are developing new modeling techniques that the business may eventually leverage for competitive advantage.
Data Analyst vs. Data Scientist Salaries
Due to their specialized technical skills, data scientists generally command higher salaries than data analysts. According to Glassdoor, the average data analyst salary in the US is $67,377. The average data scientist salary is $117,345. Here is a comparison:
| Role | Average Salary |
|---|---|
| Data Analyst | $67,377 |
| Data Scientist | $117,345 |
Data scientists earn nearly double on average compared to data analysts. However, data analyst salaries still represent strong earnings relative to many other common business roles. With some additional skills development, data analysts can sometimes transition into data science positions to advance their pay.
Data Analyst vs. Data Scientist LinkedIn Profiles
LinkedIn provides useful insights into the differences between data analysts and scientists based on how people in each role brand themselves on their profiles. Here are some key differences in LinkedIn profiles:
Headlines
Data analysts tend to have headlines focused on business roles like “Data Analyst | Operations Researcher”, while data scientists highlight technical skills like “Data Science Consultant | AI & Machine Learning”.
Skills Sections
In their skills sections, data analysts list skills like Excel, Tableau, SQL, statistics, data visualization and communication. Data scientists emphasize technical skills like Python, R, TensorFlow, neural networks, optimization algorithms and modeling.
Past Positions
For past roles, data analysts often have titles like Business Analyst, Operations Analyst, or Marketing Analyst. Data scientists commonly have titles like Machine Learning Engineer, Data Science Consultant, Statistical Modeler or Research Scientist.
Education
Data analysts frequently have degrees in business, communications, economics, statistics or related fields. Data scientist profiles tend to highlight technical degrees like computer science, applied mathematics, statistics, physics and engineering.
LinkedIn Connections
On average, data analysts on LinkedIn have more connections than data scientists. This may be because data analyst roles have been around longer and are more numerous. Data scientists are a newer, more specialized role. Here is a comparison of average connections:
| Role | Average # of Connections |
|---|---|
| Data Analyst | 673 |
| Data Scientist | 532 |
Data analysts tend to accumulate more connections over time versus data scientists who have a more specialized personal network.
Career Advancement Opportunities
What are the potential career growth opportunities for data analysts versus data scientists? Here is a comparison of common career advancement paths:
Data Analyst
- Senior Data Analyst: Takes on more complex analysis and manages junior analysts.
- Analytics Manager: Leads a team of data analysts and oversees major analytics projects.
- Business Intelligence Developer: Builds data models, dashboards, and BI tools to enhance data insights.
- Data Scientist: Transitions into a more technical data science role with additional skills.
Data Scientist
- Senior Data Scientist: Leads complex modeling and methodology development.
- Principal Data Scientist: Guides data science direction and strategy across the company.
- Machine Learning Engineer: Focuses on developing and implementing ML models and products.
- Data Science Manager: Manages a team of data scientists and leads strategic projects.
Data analysts have clear upward mobility into data science as they build more technical capabilities. Data scientists can move into specialized roles like ML engineering or take on leadership as principal data scientists and managers.
Job Market Outlook
Both data analysts and data scientists have strong job outlooks and will be in high demand for years to come. Here are some projections on job growth:
| Role | Expected Job Growth (through 2029) |
|---|---|
| Data Analyst | +17% |
| Data Scientist | +28% |
Data scientist roles are projected to grow faster than data analyst roles over the next decade. However, data analysts still have strong prospects with projected growth much faster than the average for all occupations. Rising data volumes, AI adoption, and analytics needs will drive demand for both roles.
Conclusions and Key Takeaways
In summary, data analysts and data scientists have some overlapping duties like analyzing data, visualization and programming.
