Innumerable jobs are constantly cropping up in various new verticals such as datasets and data visualization that offer critical insights into voluminous data. Consequently, as a result of this, two flourishing career paths that have shaped up in response to the scaled emphasis on artificial intelligence and business analytics is that of data analytics vs data science.

Data analysts and data scientists were two of the most high-paid professions in 2021. Also, as per the World Economic Forum Future of Jobs Report 2020, data analyst and data scientists held the number one position owing to their increasing demand across industries, and this was subsequently followed by AI and machine learning specialists.

While there’s plenty of interest in data professionals, but these two professions may sound synonymous to many. However, that isn’t the case as there are quite a few differences between data analyst and data scientist, the crucial one being that while a data analyst closely works with data visualization and statistical analysis to better understand data and identify trends, but a data scientist on the contrary, is responsible for developing frameworks and algorithms to collect data that the business could use.

If you find this interesting and would like to further know about these professions, then this detailed blog endeavors to throw light on various important dimensions of the data analyst vs data scientist job profile, their responsibilities, salary, and more. We have expounded in detail about all these crucial aspects that you must know about before you decide to opt for either of these two programs. So make sure to give this blog a read and then make the right choice for yourself.

Data Analyst vs Data Scientist : Job Profile

Data Analyst :

A data analyst helps collect and organize data and thereby obtain statistical information from the data accumulated. Data analysts are also responsible for creating detailed reports and visualisation and presenting the voluminous data in a lucid manner. This is typically in the form of charts, tables and graphs so as to make it easier for other people to interpret and use the data. These data analysts therefore assist an organisation to work around crucial data insights that may in turn help shape up the future business decisions.

They use data manipulation techniques to better analyse and interpret the complex data sets to help businesses make better decisions. Furthermore, the job profile of a data analyst involves answering questions about business operations. They help enterprises improve their overall work operations in order to increase their productivity and profitability. For instance, a data analyst may take the results obtained from a market research survey and then see how those numbers could be extrapolated to the wider target market. The survey results can in turn help a data analyst guide an enterprise to function optimally.

Therefore, some day-to-day tasks of a data analyst may include :

• Acquiring data from primary and secondary sources.
• Cleaning and reorganising data for better analysis.
• Collaborating with organizational leaders to recognize the informational requirements.
• Meticulously analyzing data sets to identify trends and patterns that could be translated into actionable insights.
• Furnishing findings in an easy-to-understand manner to help an enterprise take informed data-driven decisions.

Data Scientist :

A data scientist is a professional who closely analyses data from a business perspective, and he accordingly makes predictions to further help businesses take accurate decisions. A data scientist is someone who can predict the future based on past patterns as their job involves estimating and analysing the previous data insights. Data scientists are therefore quite astute and skilled in various computer applications, statistics, maths and modelling. They are responsible for collecting and cleaning up the data to make it more understandable and usable. These data scientists look around for patterns to create algorithms and models so that enterprises could use the data collected and accordingly interpret it in various scenarios.

These professionals more often than not work with data engineers and business leaders to put into meaningful use the data that they collect. An easy-to-understand example of data science is that of customer segmentation. Quantifying differences in customer buying behaviour and then pairing those with various demographics to better target customers can offer enterprises with the correct marketing strategies.

Some of the most common tasks of a data scientist entail the following :

• Accumulating, cleaning and processing raw data.
• Building predictive models and machine learning algorithms in order to mine big data sets.
• Creating tools and processes to evaluate and analyse data accuracy.
• Developing data visualization dashboards, tools and reports.
• Writing programs to automate the process of data collection.

While both of these professions are certainly poles apart, and we have enumerated the key differences below, but however, the data analyst and data scientist roles are very much in demand, and well these two professions also repeatedly topped the list of Glassdoor’s Best Jobs in America.

Furthermore, Angela Ahrendts, Senior VP of Retail at Apple rightly said that consumer data would be the biggest differentiator in the coming years, and it is therefore imperative for businesses to unlock the actual potential of data and use it strategically. Data analysts and data scientists are certainly the linchpins who help do so.

Now here’s a succinct overview of the major differences between data analyst and data scientist.
