- 2. Data Science refers to the art of drawing insights from Raw Data that assists Business leaders and Decision-makers in data-driven decision-making. For all the Students and Young Professionals, curious about what is data science and what’s the career prospects in this industry, this complete beginner’s guide to data science will answer all your queries. So, let’s explore the vast world of Data Science. Data Science is a multidisciplinary field and consists of various fields of expertise including computer science, mathematics & statistics, and domain knowledge to efficiently extract meaningful insights from data. According to a report by IBM, 90% of organizations have reported an increase in usage of data science technology for their business operations in the past year. This increase in the use of data science can be directly attributed to the increase in the volume of data. The amount of data generated daily is growing at an astounding rate and it is expected to reach 175 zettabytes by 2025, predicts IDC. Be it social media interaction, financial transactions, medical records, or scientific research, data holds immense value for organizations to derive insights that can potentially revolutionize all industries, and transform the way we live, work, and make decisions. INTRODUCTION TO DATA SCIENCE DATA SCIENCE WORKFLOW Here are the common steps followed in any data science project’s workflow. PROBLEM STATEMENT AND DATA COLLECTION The data science journey begins by identifying the particular problem the organizations want to solve with the help of data and data science. Then data science professionals start their jobs including data engineers and data scientists finding the relevant source of data. data can be collected through internal databases, external APIs, web scrapping, physical documents, etc. STEP 01 WHEN WE HAVE ALL DATA ONLINE IT WILL BE GREAT FOR HUMANITY. IT IS A PREREQUISITE TO SOLVING MANY PROBLEMS THAT HUMANKIND FACES.” - Robert Cailliau Informatics Engineer and Computer Scientist who helped to develop the World Wide Web © Copyright 2024.

- 3. EXPLORATORY DATA ANALYSIS (EDA) EDA is all about knowing the data. in this step, data science professionals use statistical techniques, visualizations like histograms and scatter plots, and other exploratory techniques to find the patterns, trends, and relationships in their data. STEP 02 DATA CLEANING AND PRE-PROCESSING Often the data collected from real-world situations are messed up. The datasets can have missing values, errors, or incorrect values. It needs cleaning and preprocessing before it is sent for analysis. STEP 03 DATA MODELING AND MACHINE LEARNING Data scientists use machine learning algorithms to learn from data and make predictions. The three main categories of machine learning are supervised learning, unsupervised learning, and reinforcement learning. STEP 04 MODEL EVALUATION AND DEPLOYMENT Once the data science model is ready, they are continuously evaluated and fine-tuned for maximum performance using metrics like accuracy, precision, recall, etc. This ensures the model is reliable before deploying for real-world applications. STEP 05 TOP JOB ROLES IN DATA SCIENCE Some of the most popular job roles in the data science industry include: Data Analyst Machine Learning Engineer Database Administrator Data Engineer Data Scientist/ Senior Data Scientists Chief Data Officer Machine Learning Scientist Business Intelligence Analyst Data Visualization/ Data Storytelling Specialist Data and Analytics Manager Data Architect Data Quality Manager © Copyright 2024.
