While both data analysts & data scientists analyze and interpret data, the two have distinct specializations and duties. A data analyst's job is to gather information, process it, and analyze the results so that conclusions may be drawn and business decisions can be made. Data analysts often have a stronger foundation in statistics, while data scientists also have a strong experience in computer science & programming.
The duties and responsibilities of data analytics and business intelligence are distinct, with the former focused on data analysis to guide business choices and the latter employing predictive modeling to detect future patterns and consequences.
Data Analyst → In order to provide insightful analysis & suggestions for their organizations, data analysts must collect, process, and conduct statistical studies on massive datasets. Like:
Modeling Data - Building and using mathematical models for forecasting purposes.
Maintenance of High-Quality Data - Validating that information is correct, complete, and consistent.
Compiling Information - Combining information from multiple databases to reveal hidden trends and patterns in company operations.
Data Scientist → Data scientists create, test, and deploy complex analytical methods and algorithms to address real-world business challenges. Like -
Exploration and Data Gathering - Analysis including the gathering and examination of information from diverse sources for the purpose of identifying patterns and linkages.
Extraction of data - The process of preparing data for analysis by correcting and enhancing it.
Analysis and Modeling - Creating and deploying complex algorithms and models to study data and foresee results.
Data visualization - producing visuals to help communicate findings to key stakeholders.
Communication - Sharing findings and suggestions with others across the company, even those who aren't experts in the field.
Application - Collaborating with programmers and engineers to put models and algorithms into working software.
Having a bachelor's degree and work experience in data collection, processing, and analysis is required for a career as a data analyst. Typical majors for data analysts include statistics, mathematics, economics, & computer science. Data scientists, on the other hand, have master's or doctoral degrees in a quantitative subject like statistics, mathematics, computer science, or machine learning, and have worked with complex analytics models and algorithms in practice.
Education → Experts in data analysis usually hold a bachelor's degree in a quantitative discipline like statistics, mathematics, economics, or computer science. Certified professionals in a relevant field are common among data analysts. The educational background of a data scientist, on the other hand, is often at the doctoral level in a quantitative subject such as statistics, mathematics, computer science, or machine learning.
Work Experience → Most data analysts have prior experience working in a commercial setting, preferably in a specialized field like healthcare, finance, or marketing, where data collection, processing, and analysis are commonplace. On the other hand, data scientists have often worked in a research or academic setting where they developed and implemented complex analytics models and algorithms. The ability to work with massive datasets and data visualization tools is also common among these individuals.
Expertise in software like Excel, SQL, & Tableau is helpful, but not required for a career as a data analyst. Conversely, data scientists need to be proficient in statistics, machine learning, a programming language like Python or R, and familiarity with big data tools like Hadoop or Spark. They must also be able to interpret technical findings and turn them into useful information.
Data Analyst Skills → Excel, SQL, & Tableau expertise is a plus.
Data Scientist Skills → Knowledgeable in the fields of statistics, machine learning, and forecasting.
