Data science is a rapidly growing field, and there is a high demand for data scientists across a wide range of industries. This means that there are many job opportunities available, and the demand for data scientists is expected to continue to grow in the future. According to Glassdoor, the average salary for a data scientist in the United States is $120,000 per year [1] and INR 10,25,000 per annum in India [2]. To land and learn, let us know more details about data science.

What is Data Science?

Data science[3] is an interdisciplinary field that involves the extraction of insights and knowledge from structured and unstructured data. It encompasses a wide range of techniques and tools from various fields, such as statistics, machine learning, computer science, and domain-specific expertise. Learning data science involves several steps, including data collection, cleaning, and pre-processing, data exploration and visualization, modelling, and deployment.

The process starts by collecting and gathering data from various sources, such as databases, social media, and sensors. Once the data is collected, it is cleaned and pre-processed to remove any errors or inconsistencies. After that, the data is explored and visualised to gain insights and understand patterns. Then, data scientists use various machine learning algorithms and techniques to develop models that can make predictions and automate decision-making. Finally, the models are deployed to be used in real-world applications.

Data science plays a vital role in many industries, such as finance, healthcare, retail, transportation, and more. It is used to make predictions, automate decision-making, and optimise processes. For example, in finance, data science is used for risk management; in healthcare, it is used for personalised medicine; and in retail, it is used for personalised marketing and recommendation systems. In this blog, we will discuss where to learn data science online, how to land and learn data science by internship for practical exposure, and finally, we will also discuss the benefits.
