Data analytics is a relatively new technology with wide applications. You can find a large number of students opting for data analytics training and certification. Organizations, too, stress on a data analytics certification if you are trying for a job as an analyst.
But, what is data analytics? What does a Data Analyst do? And how a data analytics certification can help build a successful career as a Data Analyst? Today we’ll answer such questions.
What do Data Analysts do?
A Data Analyst job entails using a data-driven approach to solve business problems and optimizing business processes. Data Analysts use data in multiple forms, and from various sources and look for patterns and trends in that data using advanced analytical tools. They then analyze and report this data in a way that is understandable by the project stakeholders.
What are the types of data analytics?
There are four major types of data analytics-
- Descriptive data analytics
This type of data analytics is used to assess what happened in the past and the factors that might have influenced it. It involves sifting through data sets that have already been aggregated for trends and patterns. Examples of this include monthly revenue reports and KPI dashboards.
- Diagnostic data analytics
This type of data analytics builds on descriptive data analytics to find out the cause. It involves making more connections between the data and identifying the patterns of behavior. Examples include checking why a particular product performed well in the last quarter and which marketing activities proved to be most effective.
- Predictive data analytics
Predictive analytics uses the data gathered and the insights from the previous steps to predict the future trend. It relies on statistical modelling. The accuracy of the prediction is proportional to the quality of the data. Examples include sales forecasts and risk assessment.
- Prescriptive data analytics
Prescriptive data analytics combines insights from all the aforementioned types of data analytics to chart a future course of action and solve business problems. It is the most advanced type and requires extensive manpower and technology. Examples include AI systems used for decision making.
What are the responsibilities of a Data Analyst?
A Data Analyst’s roles and responsibilities can be diverse and varied depending on the company and the field. Here are some of the basic job responsibilities of a Data Analyst-
- The Data Analyst is responsible for collecting data from multiple sources. This step also involves checking for discrepancies and cleaning the data and making it ready to be processed by the machine.
- Data Analysts use data analytics tools to process and analyze data and identify patterns and trends. They even leverage this data to find answers to a particular business problem.
- Reporting is an integral part of a Data Analyst’s job. They have to convert results into diagrams, graphs, charts, maps, and other visual representations to ensure that all the stakeholders easily understand it.
- They also need to collaborate with engineers and developers and the business teams to understand the problem and use their data analytics skills to solve it.
For performing these functions effectively, a Data Analyst needs to have specific skills. If you are looking to become a Data Analyst, you would need to polish the skills given below.
