For data analysts In the retail industry, while the job title may be the same as the healthcare field, the skill set required to succeed is slightly different. In retail, the analyst will be tasked with constructing algorithms to optimize efficiency of the in-store experience, developing market tests to calculate and evaluate the impact of in-store marketing efforts, and creating dashboards and other visualization tools to help managers and other decision-makers within the company. With these advanced analytics, retailers can discover trends, solve problems and make well-informed decisions.

An example of a retailer using analytics is Walmart, who in 2017 introduced five ways in which big data was installed to enhance the consumer experience and improve operations:

  1. make the Walmart pharmacies more efficient,
  2. improve store checkout,
  3. better manage the steps of the supply chain,
  4. optimize product assortment, and
  5. personalize the shopping experience.

In the words of Walmart, “whether it’s analyzing the transportation route for a supply chain or using data to optimize pricing, big data analytics will continue to be a key way for Walmart to enhance the customer experience.” This is just one example of a retailer using the capabilities and strategic advantages provided through data analytics; proof that the rise of data analytics jobs will only continue within the retail industry.

In retail, there’s a heavier focus on the ability to handle large data sets and inventory management. Therefore, the job seeker in this industry should have a background in computer science, statistics or mathematics. They should also possess the ability to use visualization software, like Looker or Tableau. Candidates should be fluent in writing SQL, Python or R to manipulate data sets, answer questions and drive end-to-end complete analysis that helps accelerate the business and discovery inefficiencies in the operational process.

Data Analysts in Banking and Finance

For data analysts in banking and finance, there has always been a need for talented data analysts. But though they have often been thought of as simply quantitative consultants, data analysts now have greater responsibilities than ever before. Still expected to organize and analyze large amounts of data to draw meaningful insights, a data analyst is also expected to be proactive in developing modeling techniques to make the business processes smarter, and to be more aware of future trends. Additionally, analysts within finance are expected to communicate these trends—along with other data-driven discoveries about performance using predictive analytics—to stakeholders who in turn expect the financial firm to adjust according to the data’s directives. Data analysis within the financial sector has new opportunities to expand thanks to blockchain and data mining; exciting new frontiers of data-driven technology.

The financial industry uses data sets similar in size and scope to retail. However, banking analysts are expected to be more advanced in their knowledge and technological background. They will use more programming languages, be expected to understand machine learning techniques and algorithms and have substantial knowledge in applied statistics like distributions, statistical testing and regression. Additional responsibilities for data scientists in finance include using big data frameworks (like Apache Hadoop, Apache Spark, etc.), building and optimizing “big data” data pipelines, and utilizing data visualization tools. Also, job seekers should have proficiency in using query languages such as SQL, Hive and Impala. While these programs may be foreign to many students and young professionals, knowledge of these tools can be obtained through a variety of advanced education programs.

Data Analysts in Manufacturing

Analysts in manufacturing are studying data sets and creating models to predict trends and patterns involving customer behavior, the effects of seasonality and other threats to optimization and efficiency, similar to retail. However, working in manufacturing also requires a data analyst to develop frameworks and Kew Performance Indicator (KPI) metrics to monitor business and operational performance. They are also responsible for designing and maintaining databases to support new business models. An example of how big data is used to help manufacturing companies is IBM introducing artificial intelligence software that empowers manufacturing businesses to learn about the productivity of their operation, prepare for potential equipment maintenance using predictive tools and study the evolution of the marketplace for adjustments to the company’s business offerings and efforts.

Manufacturing companies seek individuals with a variety of skills and experiences. The desired skills listed for data analysts in manufacturing include the ability to merge mixed data from disparate sources and use that data to illustrate information stories in various media (Google Sheets, Tableau, etc.) that aid in the development of strategic initiatives and generate clear insights. Additionally, candidates should also have experience with scripting languages, such as Python or R, or visualization software, such as Tableau or Qlik.

While industries like manufacturing, finance, retail and healthcare may be the more traditional areas for data analytical jobs, the need for individuals with data analytical skills has spread to other industries.

Data Analysts in Government

Many agencies utilize data to measure and monitor economics, healthcare, education, military and security, the census, planning and budgeting, crime, environment and other aspects of society. Here are some examples of government agencies using data analytics:

For those curious how to become a data analyst, let’s explore the career path in greater detail.

How to Become a Data Analyst

Let’s examine the difference between a data scientist and a data analyst. While both roles exist within the larger data science community, they do represent two distinctive roles and career paths.

A data scientist formulates hypotheses, tests them, and then from these results makes business and organizational insights. Data scientists use unstructured data from multiple, often disconnected sources and sorts that data to make forecasts through predictive modeling.

In comparison, a data analyst answers specific questions related to a business. For example, “What is the greatest source of revenue for the company?”, or “What will the company’s costs be in the coming year?” Furthermore, a data analyst works primarily with structured data from a single source, organizing and sorting the data to solve challenges the company faces by providing historical analysis and data-driven decision-making.

To become a data analyst, many people first earn a bachelor’s degree in a related field, such as computer science, social sciences, the physical sciences or statistics. The most common fields of study are mathematics and statistics (32%), followed by computer science (19%) and Engineering (16%). After earning a bachelor’s degree, one will then be expected to earn a master’s degree. Those who pursue a degree focused on data analytics will be expected to learn how to analyze complex data sets, as well as design, implement and evaluate analytical solutions.

The career path for a data analyst can often begin with an entry-level position as a research assistant or junior data analyst. This involves working with data sets, utilizing quantitative programs to gather qualitative data and creating data visualizations and dashboards. The average salary for a research assistant ranges from $25,000 to $65,000 and is often filled by graduate students or recent college graduates.

A common next step in the career path is to work as a software engineer. Though not a requirement, software engineering provides experience in designing, developing, maintaining, testing and evaluating computer programs that benefit long-term career growth.
