While resources are available in plenty to study any field of knowledge, it is important to know exactly what to study. Let’s first take a look at the skills required in the field of Data Science.
Required Skills in Data Science
Data Science is not a single discipline, rather an amalgamation of various disciplines working together to achieve a single goal, i.e., transforming data into an asset. To have complete mastery over all the disciplines will be overstretching it. So, depending on individual strengths, you can pursue a set of skills of your choice to contribute to the field of Data Science.
Below are the skill sets that are desired in a Data Science professional:
- Fundamentals of Data Science: Before jumping on the bandwagon, it is essential to cover the foundational concepts and ideas to truly understand the essence of Data Science.
- Statistics and probability: Statistics is an age-old indispensable concept and a powerful tool in the field of Data Science that executes technical data analysis to offer concrete conclusions.
- Programming: The only way to communicate with machines is through programming, so it is an essential skill to have. You can pick up any from these: Python, R, Julia, etc.
- Data manipulation: It involves the cleaning of data and transforming it into a better format for analysis.
- Data analysis: Data analysis is the process of finally understanding all about the data, and it typically requires skills in Excel, SQL, Pandas in Python, etc.
- Data visualization: You must be familiar with various plots and charts, including pie charts, histograms, bar charts, waterfall charts, etc. Tableau is an excellent tool for data visualization.
- Machine Learning: One of the core skills to have in Data Science, Machine Learning is used to build predictive models with high accuracy and low errors. Machine Learning experts have a good understanding of data modeling, Machine Learning Algorithms, distributed computing, etc.
- Deep Learning: A good grip on programming (preferably Python), linear algebra, and mathematics is required for working with Deep Learning. Also, you must know how to handle libraries such as TensorFlow, PyTorch, and Keras.
- Big Data: Organizations are trying to tackle data by adopting Big Data Analytics, and in this domain, Hadoop, Hive, Spark, Apache Storm, and Flink are some of the frameworks and tools that are required.
- Software engineering: You don’t need to be a software engineer, but knowing thebasics of software engineering, such as the lifecycle of software development projects, compilers, time-space complexity, data types, etc., goes a long way.
If you are seeking resources for Data Science, you may find those that include everything, or you will find good ones that are best at explaining separate parts of it. Either way, there are countless ways you can master Data Science. Following are some of the freely available Data Science resources and platforms that are aimed at helping learners and professionals equally.
