At a glance

If you are interested in becoming a data analyst or data scientist, it’s essential to understand the differences between these two related but distinct careers. 

Data analytics

Data analytics refers to assessing information to find trends, patterns or other evidence that can help an organization solve a particular problem, increase operational efficiency, save money or reach some other goal. Analytics projects often require communicating findings to the decision-makers in a company or organization. 

Data analysts often need to develop charts and other visuals that communicate and support their findings. 

According to the U.S. Bureau of Labor Statistics (BLS), analytics is a growing field because companies use the findings of analysts to make informed strategic decisions, manage risks, develop budget forecasts and better define targets of marketing campaigns. 

Types of data analytics

Data analysts try to find answers to questions in large data sets, but the approach can differ depending on the project. 

Here’s a look at the four primary types of data analytics:  

  • Descriptive analytics answer questions about what happened in a specific situation by looking at the data surrounding the occurrence. Analysts use this information to explain outcomes, often related to key performance indicators (KPIs), which measure progress toward a final goal.
  • Diagnostic analytics complements descriptive analytics and helps analysts understand why an event happened the way it did. This type of analytics digs deeper into the findings of the descriptive analysis to discover the reasons behind an event. For instance, diagnostic analytics may help a company understand why specific KPIs improved or declined. 
  • Predictive analytics helps forecast what could happen in the future. This type of analysis uses historical data, including past trends, to identify patterns that are likely to continue. 
  • Prescriptive analytics helps answer questions about what’s needed to solve an issue or reach a goal. This type of analytics aims to identify specific actions an organization can take to achieve future goals or objectives. 

When applying for a job as a data analyst, it can be helpful to be proficient in all four types of analysis.

Applications of data analytics

Organizations and businesses use data analytics for a wide range of purposes. Here are some of the most common applications for data analytics. 

  • Risk management: Through research, an analyst identifies possible risks (financial, cybercriminal and industrial) a business faces and makes cost-effective recommendations to help manage them. 
  • Budgeting and forecasting: Through predictive analysis based on an organization’s historical information, analysts provide insights to help a company set realistic goals and budgets while identifying areas for improvement.  
  • Marketing and sales: Descriptive and diagnostic data analysis helps businesses identify and track useful marketing and sales metrics, such as conversion rates. Using historical data from past campaigns, analysts find areas for improvement.  
  • Product development: Data analysts help businesses develop better products by using data analytics to assess trends in their industry and define consumer needs. 

Those are some of the most common applications for data analytics. However, companies rely on data analysts for other purposes as well. If you work in the field of data analytics, your focus may vary depending on your employer’s needs and industry. 

Duties of a data analyst

The specific duties of data analysts depend on the type of organization they work for and the extent to which the organization adopts data-driven strategies and decision-making. Key responsibilities of data analysts include:

  • Using statistical tools to interpret data while paying attention to trends and patterns to glean valuable insights. 
  • Mining data from primary and secondary sources and reorganizing it into formats that are useful for the analysis project.
  • Designing and maintaining data systems and databases, including fixing data problems such as coding errors.
  • Preparing reports that offer data-supported insights and communicate trends, patterns and predictions.
  • Collaborating with other IT professionals in an organization (such as programmers and engineers) to identify opportunities for process improvements, recommend system modifications and develop data-management practices.

Data analysts present insights that can affect the high-level decisions of a company. This role and the responsibilities require a solid educational foundation in technology as well as certain skills. If you’re interested in a career in data analytics, you can pursue a technology degree to gain the right knowledge. 

BLS notes that because few schools offer degrees in data analytics, students may want to consider similar degree programs. You might also consider an education in a related field of specialization, such as cybersecurity. Earning a Bachelor of Science in Cybersecurity and then enrolling in a Master of Science in Cybersecurity can further enhance your knowledge in cybersecurity. With the right education, you’ll improve your ability to demonstrate deeper skills and specialized knowledge for applying data analytics in a targeted way.

Data science

Data science involves the design and creation of data modeling techniques and processes. The goal of a data scientist is to collect and organize information into forms that are useful for analysis or other purposes.

The data science toolbox includes algorithms and mathematical models that analyze and interpret data sets automatically. The goal of data scientists is to use these tools to create data-driven solutions for businesses or organizations. 

In other words, data scientists lay the groundwork for all the different types of data analysis and data usage within a company or organization. 

Types of data science

Data science is a broad and developing field, and data scientists can focus on any of the following specialties: 

  • Data mining involves the analysis of large sets of data to produce meaningful information. Data miners often create mathematical models that find and define patterns, trends and correlations in raw data. 
  • Data engineering focuses on building and maintaining frameworks that transform data into useful formats. This specialty involves setting up database systems for collecting and organizing data from different places into one usable collection.
  • Data architecture involves designing, creating and managing a complete digital framework for an organization’s data. Data architects often create the larger system in which specialist data scientists work. 
  • Machine learning involves using data to improve the performance of computer-driven systems. This data science specialty focuses on creating algorithms that allow computers to interpret data and adjust operations according to the new information. 

Regardless of their specialty, data scientists need to develop knowledge of both mathematics and computer systems. 

Applications of data science

Data science has a wide range of applications, and data scientists can specialize in a variety of areas, depending on the needs of their employer. That said, data scientists always focus on facilitating data-driven activities for their employers or clients. Here are some common foci in the field of data science: 

  • Data wrangling involves sourcing, cleaning and structuring data into various data sets that are accessible and ready for analysis. 
  • Statistical modeling involves running the data through a set of mathematical equations to identify relationships, make predictions or assess performance. For example, regression and clustering models identify relationships between variables in the data and help put information in a useful, visualized format. 
  • Programming involves creating computer programs that can function with databases to access, organize and filter information. Data scientists use languages such as SQL and Python when programming tools for this purpose. 

Duties of a data scientist

The duties of data scientists depend on their area of focus. Data scientists can work, for example, in the finance or medical industries or at academic institutions. As more companies adopt data-driven operations, these professionals are in high demand.
