What is a Data Analyst?

“Behind each data point is a living, breathing human."- Shafqat Islam, CEO of NewsCred.

Still wondering, who is a data analyst? That living, breathing human is a data analyst. Organizations count on data analysts to help them make profitable business decisions based on data. A data analyst is an umbrella term and it can also include Business Analyst, Corporate Strategy Analyst, Marketing Analyst, Sales Analyst, Finance Analyst, Management Reporting, Business Product Analyst, Social Media Data Analyst, Budget Analyst, and much more.

What is a Data Analyst

Data and numbers have an important story to tell. They rely on a data analyst to give them a clear and convincing voice. A data analyst plays a critical role in guiding businesses in improving the products, services, or business processes by delivering data-driven reports and recommendations to stakeholders. For any data science project to be executed successfully, once the business analyst completes requirements gathering, the requirements are sent to a data analyst. A data analyst is a detective who identifies what all data is important to solve the business use case and from where we can get the data. He/she also suggests other sources of data that can be useful for solving a given business use case. A data analyst takes the data from various sources and tries to understand/interpret the trends and patterns in it.

Define the Business Problem

Understanding the business goals is a crucial thing every data analyst does because it forms the basis of their analysis. A data analyst understands what the client requirements are- do they need a dashboard or they need a report or they need some kind of analysis on their product to provide some recommendation or anything else. After having good know-how of the client’s needs, they put in a plan of action –

  • Where is this data coming from?
  • When are they getting this data?
  • Where are they putting this data within the organization?
  • Time stream for all these steps.

It is often a data analyst’s job to communicate the plan of action to the team.

Collect Data

Having clearly defined the business problem, a data analyst determines what data needs to be collected from existing data sources or databases. Collecting data in the real world is not as easy as downloading a dataset from Kaggle. A data analyst does not always find perfectly pre-processed data to solve the business use case. The data can come from multiple sources: a flat file, an API, or a SQL backup. A data analyst collates all the data in one place and works with developers to create an ETL pipeline for the same by setting up business rules to transform the data on it should look once it is loaded into the system. Having quality data and relevant data are vital to the data analysis process without which a data analysts’ insights would be irrelevant. A data analyst working at a start-up or a small company that has not invested in data infrastructure keeps a constant check on whether the company is collecting the right data or not. He/she also keeps an eye out for additional data sources to ensure data diversity throughout the analytics process.

Clean Data

Data is always messy, and data cleaning is important to make the data usable for later processes. Cleaning data is the most important but time-consuming and the least enjoyable part of a data analyst’s job. A data analyst spends as much as 90% of the time cleaning data (fixing structural errors, handling missing data, removing irrelevant observations, and filtering out unwanted outliers) because clean data is critical for gleaning valuable and accurate insights. So, if you are venturing out on the path of becoming a data analyst grab as many opportunities as you can to practice data cleaning skills on diverse analytics projects. Still not convinced why data cleaning is important to a data analyst job role, let’s understand it with an example.

Suppose that a data analyst collects data of different customers on Amazon who buy products produced by its in-house brand Symbol. Now the goal is to understand which products people buy the most so accordingly, the business can scale up the production of those products. However, if the data is corrupted or does not contain any valid values then the analysis would result in misguided decisions. Data cleaning involves normalizing the data, standardizing the data, and validating it so that it can be used for generating reports and visualizations in the later part of the analysis process.

Set Data Up for Visualizations and Reports

The next most important thing a data analyst does is creating views for setting up the data for reporting. A view lets a data analyst combine the data from multiple tables into one and then select a subset of the data that is actually needed for creating visualizations or reports. Each view is formatted differently based on what it is going to be used for in the visualization or report.

Creating Reports and Visualizations

As a data analyst, your time will be spent in reporting. It could be either maintaining existing reports and pushing them out to the business or creating new reports from scratch. These reports can be in the form of PowerPoint Decks, Excel Dashboards, or a report from any visualization tool like Tableau, Power BI, or QlikView. Some data analysts even use SQL to create reports and automate the process of creating reports with the latest data (weekly or monthly) through stored procedures. A data analyst creates reports or visualizations to ensure they have solved the defined business problem they were intended to solve.
