What are some common data analyst responsibilities?

A day in the life of a data analyst isn’t as simple as putting numbers on a spreadsheet. As the gatekeeper of an organization’s vast amount of data, a data analyst plays a critical role in informing strategic business decisions and improving the overall health of a business.

To be successful in a career in data analytics, analysts must have a combination of strong analytical, technical, and communication skills. Below is an overview of some of the common data analyst day-to-day responsibilities.

Identifying the problem

Before a data analyst can begin collecting and interpreting any data set, they must first identify and define the business problem or objective. To do this, analysts need a strong understanding of the businesses’ inner workings, processes, and goals. Analysts often collaborate and brainstorm with other departments to identify existing business challenges or isolate new opportunities for improvement. Once identified, analysts can begin gathering data to understand the problem better.

Defining data quality criteria

Data quality criteria are used to determine whether a system’s data is accurate, complete, consistent, and reliable. Defining data quality criteria is essential for a data analyst’s data collection process. Bad data can significantly impact a business’s operations and decision-making processes. Companies can make poor decisions or ineffective strategies if inaccurate or incomplete data is collected. That is why data analysts must define data quality criteria before continuing their analytical process.

 Establishing data processes

Establishing processes for completing a task efficiently and effectively is necessary for nearly every type of job. Just as a chef uses a process to create a recipe, so does a data analyst for collecting and organizing data. Data analysts rely heavily on their ability to efficiently manage and manipulate large quantities of data to achieve their objectives. Often, the data is complex and requires the analyst to establish a framework or “process” for breaking down the information into usable, insightful information. Data analysts often work with other people, such as engineers and data architects, to implement process improvements, make system modifications and develop more thorough documentation methods.

Cleaning Data

Cleaning and preparing data are a large part of any data analyst’s workday. To ensure credibility and accuracy in their findings, analysts must clean the data collected by removing any duplicates, errors, or outliers. Data cleaning is an invaluable skill for data analysts to master. It is one of the most critical steps to preparing accurate models for analysis. Just as mentioned above, bad data leads to incorrect or misleading conclusions. Because of this, proper data cleaning skills are crucial to a data analyst’s success.

 Analyzing data

The term “data” refers to a business’s large, diverse data sets. This data type is often too large or complex to process with traditional data analysis methods. That is where the data analyst comes in. The data analyst is responsible for using their knowledge of programming languages, like Python or R, to handle this type of data and perform complex equations. In addition to programming skills, analysts need strong critical thinking skills to process and analyze big data sets. Analysts use critical thinking to uncover hidden patterns, identify correlations, and extract insights beyond just numbers themselves.

With data analytics, an organization can harness the knowledge of these complex data sets and identify new opportunities to improve its end-user experience.

Generating reports

Generating reports is a primary responsibility of a data analyst. Once the data analyst has gathered the data, cleaned it, and analyzed the results, it’s time to present their findings to the appropriate parties. To do this, analysts build reports that help comprehensively illustrate their analysis results. Data analysts also generate reports to identify patterns and make predictions. Reports allow the data analyst to describe what is causing the business problem and provide usable, actionable solutions to inform improvements.

Data analysts use various reporting tools to achieve their presentation objectives. Extensive knowledge of reporting tools like SQL, Excel, Tableau, and Python is essential to the success of any data analyst. Learn more about advancing your data analytics skills with a Tableau Data Analytics Certificate here.
