Are you wondering which of these roles might suit you better or if there is even a significant difference between these different roles?

This article may be just what you need to clarify some of the key differences in these roles. We focus on the differences between data analysts and data scientists. A disclaimer: What is covered in this article may not be completely relevant to every role called data analyst or data scientist, nor is it an exhaustive list of the responsibilities you may face. It’s true that these roles can vary depending on the company and industry, and ultimately the best way to find a job that’s right for you is to take the time to read the entire job description.

What Is The Role Of Data Analyst

As a data analyst, you will be heavily involved in using data to answer a variety of different business questions asked by various stakeholders in the company. To get these answers, you’ll often be involved in several other tasks as part of the process. For example, many data analysts are busy collecting data from primary and secondary sources and cleaning the resulting data from less structured data sets. In some cases, you will also be expected to work with stakeholders to identify information needs. This then requires you to design and maintain data systems and databases. A data analyst can also be expected to be heavily involved in A/B testing. Sometimes data analysts need to be creative to solve business problems that lack direct forms of data. This can involve searching through different data sets and merging them to produce meaningful insights about consumers.

How To Become A Data Analyst: Navigating The Data Landscape

In terms of analysis, the role of the data analyst is much more consulting-oriented than the role of the data scientist. Therefore, data analysts are more directly connected to business unit stakeholders and often serve as a communication bridge for data scientists given the complexities that can arise in the technical elements of analysis. Additionally, data analysts are often more involved in the customer-facing elements of the business, so they may sometimes be expected to assist with presentations to customers by providing analytical elements or creating dashboards to monitor and improve business performance.

It’s even more important for data analysts to be able to derive actionable insights from data sets to help address real-world business challenges. For example, as a data analyst, you may be asked to explain why the number of new users fell in the previous month or why a particular marketing campaign performed better in certain regions. More importantly, data analysts must be able to effectively communicate these insights to various audiences. This often includes creating reports to communicate these insights and trends based on existing data. For many data analysts, being able to translate these statistical insights into immediate action for the business is key. In general, a unique experience as a data analyst is that you gain a comprehensive understanding of the business and the entire industry. This is often necessary so that the data analyst can generate meaningful insights that make sense to various stakeholders.

You can expect many data analyst job descriptions to include skills such as data mining, data warehousing, and database management. Establishing data collection structures is also essential for future analysis that can be performed on similar sets of information typically used to track the performance of business decisions made in the past. SQL and database management skills are particularly important for data analysts as part of the insights process.

In terms of skills required, data analysts can expect to use a lot of SQL, Excel, R or Python or SAS and BI software for a variety of purposes including statistical analysis, data modeling and data visualization. However, unlike data scientists, data analysts do not primarily focus on advanced data modeling techniques. Instead, data analysts usually need to be familiar with basic supervised learning models such as regression and have a good foundation in mathematics and statistics.

Data Jobs You Must Know About To Ace Your Career

Just like data analysts, data scientists work to answer a specific business question that requires data-driven insights. However, data scientists are primarily concerned with estimating unknowns and using algorithms and statistical models to answer these questions. A key difference, therefore, is the amount of coding used in data scientist roles. In this sense, data science roles can be challenging as they require a mix of technical skills and an understanding of business problems in context. A data scientist will often try out different algorithms to solve a specific problem and may even need to be familiar with pipeline automation.

Data scientists also get their hands dirty with much larger data sets than analysts and therefore must have the skills to explore and model massive amounts of unstructured data, often in parallel using languages ​​like Scala. Many data scientists eventually realize that a large part of their job involves cleaning and processing raw data from a variety of sources and ensuring that the process for implementation and prediction can be reproduced in the real world.

By and large, data analysts are more consulting-oriented, while data scientists are often more product-oriented, with the goal of building data and modeling pipelines for effective predictions in real-world product environments with a high level of accuracy.

Data scientists not only need to know SQL and Python or R, but also know how to work in the cloud with software or languages ​​such as Scala, Spark, Hadoop, AWS, Databricks, to name a few. To complement these skills, data scientists also need to be familiar with OOP, machine learning libraries, software development, and a generally more extensive technology stack, as they may need to work with older scripts and algorithms that may even need to be updated as data sets change currently.

Data Analyst Skills You Need To Get Hired

As data scientists become much more concerned with prediction problems, they are using more advanced data techniques to make predictions that satisfy both structured and unstructured data. Therefore, not only a solid foundation in mathematics and statistics is required, but also comprehensive knowledge of data acquisition, processing, visualization and, above all, knowledge of machine learning algorithms. Depending on the company, data scientists could be exposed to the full range of algorithms in areas such as natural language processing, computer vision and deep learning. Therefore, data scientists often need to have very in-depth knowledge of statistics and frameworks like TensorFlow. It is no exaggeration to say that modern society is based on data. Humanity generates a whopping two and a half trillion bytes of data (that’s 2,500,000,000,000,000,000 bytes) per day – and it seems unlikely that this metric will decline any time soon. According to a recent report from International Data Corporation (IDC), the global big data and business analytics market has grown rapidly in recent years, with global revenue increasing from $122 billion in 2015 to $189 billion increased in 2019, forecast to reach $274 billion in 2022

With this rapid expansion comes a significant opportunity to further develop your data analytics skills, for example by enrolling in a data analytics bootcamp aimed at those looking to enter the field. Digital transformation has become the buzzword of modern businesses and talented data analysts are needed now more than ever. Career opportunities exist in almost every industry, from telecommunications to manufacturing, retail, banking, healthcare and fitness.

However, a career in data analysis will not be worthwhile without extensive training and effort. Data analysts require specific skills to advance in their field, and their qualifications are primarily technology-focused. However, working professionals also need a handful of soft skills. There is no way to acquire these skills. While many individuals choose master’s programs, a growing group of students have begun enrolling in bootcamps because they are attracted by the affordable prices and short deadlines. Regardless of which path you take, you need to develop solid skills to become an in-demand data professional.
