How to Write a Data Analyst Job Description: Important Skills and Role Responsibilities

The terms may sound similar, but data analysts, data engineers and data scientists are actually very different roles.

Here’s the simplified version: Data analysts are responsible for collecting, cleaning, analyzing and reporting data; meanwhile, data engineers create and maintain architectural systems for collecting, storing, analyzing and managing large quantities of raw data; and finally, data scientists handle data collection, analysis and visualization — and sometimes build things like machine learning models.

To write a stellar job description for data analysts — and attract top candidates — you’ll need to understand their role more specifically. That’s where this guide comes in.

Data Analyst Key Responsibilities 

Data analysts gather data across a business, analyze it and translate the results into non-technical language and visualizations for team members of all backgrounds.

Data analysts are typically early in their careers and may be seeking their first job after completing a bachelor’s degree or gaining the equivalent professional experience. Common degrees for individuals in data analytics include statistics, math, computer science, physics, finance, business administration, economics or a related field.

The process of collecting and analyzing data involves identifying reliable information sources and preparing the data by removing inaccuracies, handling missing values and ensuring consistency. To do this, data analysts use tools like Excel or coding languages like SQL or Python, depending on the scope of the project. Once the data is clean, analysts move on to analysis and interpretation by identifying patterns, trends and correlations through statistical methods and visualization tools.

Individuals in this field also collaborate with other teams to translate complex data findings into action business recommendations. They must be able to communicate their work to non-technical stakeholders in a clear and concise manner.

In many cases, data analysts are also expected to:

• Create dashboards and reports for business metrics.
• Build data models to organize important information.
• Develop and maintain databases or data systems.
• Work with IT and data engineers to ensure data accuracy and system efficiency 

As they progress in their careers, data analysts may become data engineers and eventually data scientists.

Types of Data Analyst Jobs

There are many different careers and jobs that data analysts can hold. Some of the most common fields for data analysts to work in include healthcare, big data, market research, operations and intelligence. 

Let’s take a closer look at a few different types of data analyst jobs and what they do. 

1. Business Intelligence Analyst

The primary job of a business intelligence analyst is to extract valuable insights from company data. Someone in this role should be comfortable with SQL, analyzing data, as well as creating data models.

2. Marketing Analyst 

Marketing analysts help their team track the success of campaigns by using Google Analytics, custom reporting tools or other traffic analytics sites to determine the impact advertisements are making. Marketing analysts are key to marketing departments as they help understand what efforts are working and what advertisements to spend company money on. 

3. Transportation Logistics Specialist

Transportation logistics specialists can utilize a data analytics background in a variety of ways. This role relies heavily on the ability to identify efficient delivery routes for products and services. Someone in this role uses large datasets to eliminate transit bottlenecks.

Data Analyst Skills

Data analysts employ a variety of soft and technical skills throughout their careers. Like many positions, having clear communication skills and the ability to present complex information is crucial to this role. Critical thinking skills are an essential part of many jobs, and data analysts are no exception. These soft skills are especially important to data analysts because they are often responsible for presenting data to stakeholders and other teams in ways that everyone can understand.

Along with communication and critical thinking skills, data analysts will need to understand different visualization tools, coding languages and mathematical principles.

Coding Languages

Mastering coding languages like R and Python is important as they are standard in the industry. These languages also provide advanced analyses and predictive analytics on large data sets. Some coding languages data analysts need to know are: 

• C#
• Git
• Javascript
• .Net
• Python
• R

Data Visualization

A key element of a data analyst’s job is data visualization. Data visualization allows analysts to identify patterns and showcase their findings to stakeholders and other teams. This skill is crucial in shaping company decisions and roadmaps. Some data visualization tools that data analysts use include: 

• Google Analytics & Google Tag Manager
• Looker
• Microsoft Power BI
• Superset
• Tableau

Databases

Data analysts rely on databases to store, maintain and organize data. There are several types of database languages that analysts may need to learn early on in their career. SQL, one of the first database languages created in 1970, is still a standard for querying and handling data today. Some common database languages for data analysis include: 

• Apache Cassandra
• MariaDB
• MongoDB
• MySQL
• Node.js
• PostgreSQL
• Redis

Data Warehouses

Data analysts use data warehouses to perform queries and analysis on historical data. The information contained in a data warehouse can include data such as application log files and transaction applications. These tools are useful to analysts because they consolidate large datasets from many sources. Often called a “single source of truth,” a data warehouse allows a company to improve decision making based on historical insights over time. Some types of data warehouses are: 

• Amazon Redshift
• Apache Hive
• Microsoft Azure SQL Database
• Oracle Database
• Oracle Warehouse Builder
• SAP NetWeaver Business Warehouse
• Snowflake

Data Analyst Education Requirements

Although it may be possible to get a job in data analytics without a degree, having a bachelor’s degree can help candidates stand out and is often a requirement for many positions. Majoring in data analytics in an undergraduate program is a great place to start but not all universities offer this. Some alternative majors to look into include data science, computer science, applied mathematics or statistics. 

Whatever major you choose, taking courses on statistics, calculus and linear algebra will help you develop crucial skills for your career. Computer science courses with a focus on databases and statistical software will also provide a solid background to draw from. For those that have an idea of what field they’d like to work in, it’s always a good idea to take a course or two in a specific industry like healthcare or finance. 

Obtaining a master’s degree in analytics or a related field will open up more opportunities as well as senior positions. In fact, approximately 50 percent of professionals in the data science and analytics industry hold master’s degrees. Master’s degrees can help data analysts advance their visualization skills, understand how to use data in an ethical way and learn the best practices for data security.
