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 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.
