What are the four components of a Data Science Project?
Before you are out there building your internal data science practice, it is really important to understand the structure of any typical data science project. If you miss out on any of the core components of data science, then there are high chances of failure of all the efforts you put in for bringing true value to the business.
The four main components of every data science project are:
1. Data Strategy – The development of data strategy is where you determine what data you are going to collect and why you are going to do it.
2. Data Engineering – This step is about what systems and technology you will utilize to access, use, and organize the available data.
3. Data Analysis and Mathematical Models – This is considered to be the heart of data science. Here, the data is analyzed with the help of different tools and mathematical models to extract valuable insights.
4. Visualization and Operationalization – After analyzing and modeling the available data, the data is visualized to make it easy for everyone to understand and take actions based on the conclusions drawn from the analysis.
What does a data scientist major in?
There are different ways to land a career in data science. If we categorize it, in general cases, there are three ways that people usually take it up.
1. Take up a bachelor’s degree in IT, math, computer science, physics, or any other related field.
2. Get a master’s degree in the data field or any other related field.
3. Directly gain experience in the data field by working in different sectors that you intend to work in.
Which degree is considered to be the best one for data scientists?
If you are willing to build a successful career as a data scientist, you should definitely look out to opt for Computer Science with a specialisation in Data Science. It is considered to be the most well-represented degree among data scientists, with 18.3% of professionals possessing it in the field.
This isn't really shocking because you need to possess good programming skills for building a successful career in this field. Other than that, 16.3% of data science professionals possess a degree in Statistics or Math, which is again not so surprising. It is a great option to consider if you are really good at math.
