Data Scientist Road Map

What is Data Science?

Data science, in simple words, is the study of data, which includes algorithms, principles of machine learning, and various other tools. It is used to record, collect and analyze data to obtain important and useful information. Data scientists extract information and data from particular sources and examine them. These data can be from a wide range of sources such as log files, predict disease, and personalize healthcare recommendations, social media, sensors, and customer transactions.

What is a Data Scientist?

Data Scientist is a person who collects, interprets and analyzes data to help the organization in decision making is called a Data Scientist, in which analysis and calculation of the effect of data are required, for this professional expert is required. In which, software engineer needs skills like mathematic knowledge like Linear Algebra, statistics, and computer program.

A data scientist is a professional who uses scientific methods, algorithms, and tools to extract insights and knowledge from structured and unstructured data. The role of a data scientist involves the following tasks:

1. Data collection and cleaning: A data scientist collects, organizes, and cleans data from different sources. This includes identifying data sources, acquiring data, and cleaning data to remove inconsistencies, errors, and duplicates.
2. Data exploration and analysis: Data scientists use statistical and computational techniques to explore and analyze data. This includes identifying patterns, trends, and relationships in data, as well as performing statistical modeling and predictive analysis.
3. Data visualization and communication: Data scientists use data visualization techniques, such as graphs and charts, to communicate insights and findings to non-technical stakeholders. This includes summarizing findings, creating reports, and presenting results to business leaders.
4. Machine learning and artificial intelligence: Data scientists use machine learning and artificial intelligence techniques to build models that can be used to make predictions or classify data. This involves selecting appropriate algorithms, tuning parameters, and validating results.
5. Business strategy and decision-making: Data scientists use their findings to help organizations make informed decisions about their business strategy. This includes identifying opportunities for growth, optimizing processes, and minimizing risk.
