Data Science Career Outlook
By many accounts, becoming a data scientist is a highly desirable career path. From startups to Fortune 500s to government agencies, organizations are seeing the value in capitalizing on big data.
Data scientists are relatively scarce, meaning it’s now an opportune time to upskill and enter the field.
Role and Responsibilities of Data Scientist
1 Ask the right questions to begin the discovery process.Solving business problems through undirected research and framing open-ended industry questions
2. Acquire data.Extract huge volumes of structured and unstructured data. They query structured data from relational databases using programming languages such as SQL. They gather unstructured data through web scraping, APIs, and surveys.
3. Process and clean the data.Thoroughly clean data to discard irrelevant information and prepare the data for preprocessing and modeling
4. Integrate and store data.Perform exploratory data analysis (EDA) to determine how to handle missing data and to look for trends and/or opportunities
5. Initial data investigation and exploratory data analysis.Employ sophisticated analytical methods, machine learning and statistical methods to prepare data for use in predictive and prescriptive modeling
6. Choose one or more potential models and algorithms.Discovering new algorithms to solve problems and build programs to automate repetitive work
7. Apply data science techniques, such as machine learning, statistical modeling, and artificial intelligence
8. Measure and improve results.Recommend cost-effective changes to existing procedures and strategies
9. Present final result to stakeholders.Communicate predictions and findings to management and IT departments through effective data visualizations and reports
10. Make adjustments based on feedback
11. Repeat the process to solve a new problem

Data Science vs. Data Analytics
Data analysts examine data sets to identify trends and draw conclusions, Data Analysts collect large volumes of data, organize it, and analyze it to identify relevant patterns. After the analysis part is done, they strive to present their findings through data visualization methods like charts, graphs, etc. Thus, Data Analysts transform the complex insights into business-savvy language that both technical and non-technical members of an organization can understand.
Data Scientists use a combination of Mathematical, Statistical, and Machine Learning techniques to clean, process, and interpret data to extract insights from it. They design advanced data modeling processes using prototypes, ML algorithms, predictive models, and custom analysis.
