What exactly do they do?

While closely related, data science and data analysis have distinct goals and approaches. Data science, as a multidisciplinary discipline, entails using statistical methods, mathematical sciences, computer sciences, and information from specific domains to discover findings in various data sets. For example, data scientists are involved in all aspects of their work, such as data collection, cleaning, model deployment, and other related issues that are critical to problem-solving and decision-making in fields such as medicine, banking, advertising, and information technology.

The steps in the data science process are as follows: gathering data from multiple sources, conducting exploratory data analysis, developing features, building and assessing models, and implementing the models in real-world applications are the final steps. Such a broad methodology helps data scientists find relationships involving different types of variables, such as structured and unstructured values.

While, data analysts focus on analysing as well as synthesising data for making company decision process easy. Primarily they use structured data to carry out statistical analysis based on past statistics that are presented in forms of reports, dashboards, and visuals. These tasks entail data cleansing, univariate and graphical analyses, report writing, and customized ad hoc analysis for various business requirements. Data analysts are essential since they condense complex information into comprehensible forms to help organizations comprehend their performance indicators and take appropriate actions.

Briefly speaking, although these two jobs deal with data, data scientists develop and implement complex predictive analysis models. In contrast, data analysts concentrate on clarifying and exhibiting information for the purposes of managerial decisions. How they are to be specifically responsible or not within their roles will depend upon what is required by the organization and type of data projects they participate in.

Differences between data science and analyst

Data Science is a separate field from Data Analysis although they are interconnected in some ways. Here are the key differences between the two:

Scope and Goal:

Data Science: Data science is a wider area that incorporates diverse techniques of extracting information or knowledge from the set of data. Here, it encompasses more than just descriptive analytics such as data mining and usually involve large sets of data.
Data Analysis: Data analysts examine, cleanse, manipulate, and model data to extract relevant information, make decisions, and provide informed judgment through discovery and conclusions. It usually makes use of descriptive statistics and graphics.
