There were 5 exabytes of information created between the dawn of civilization and 2003, but that much information is now created every day. This is the age of data. And in this age, the data scientists are gods!!! They are the ones with extremely diverse skill sets, ranging from data management to machine learning.
These multi-talented magicians are chiefly responsible for converting the data into actionable insights by using self-created predictive models and custom analysis according to company requirements. In other words, being a data scientist is an extremely important job in the current data age.
Who is a Data Scientist?
A data scientist is a professional who is an expert in statistics, mathematics, and programming and uses their skills in numbers, math, coding, and specific field knowledge to find important information from a lot of data. They look at complicated sets of data to discover trends, patterns, and connections that help with business choices, plans, and solving problems.
Data scientists generally use programming languages like Python or R to apply statistical methods and use machine learning algorithms to study and understand data. Data scientists use their knowledge in various fields such as healthcare, technology, marketing, and others to help organizations make decisions based on meaningful information provided by data scientists by analyzing their data.
