Having a degree in data analysis is not necessarily a job requirement. However, you should fulfill the relevant background education requirements. This means a bachelor’s degree in mathematics, statistics, computer science, or finance. The next step is to put your skills into practice through projects. Get an internship or an entry-level job to practice your skills. This will make you look more employable for recruiters.
What does a data scientist do? #
A data scientist determines which questions need to be answered. The next step is identifying where to source the data to answer those questions. How is all this information processed? The structured and unstructured data go through machine learning algorithms or design predictive modeling processes. With their knowledge of business strategy and analytical skills, data scientists carry out these tasks:
Gathering and cleaning data
Automating data collection and processing
Creating mechanisms to oversee and evaluate the precision of data
Designing predictive models and machine learning algorithms for data mining
Building data visualization tools, dashboards, and reports
How to become a data scientist#
Data scientist roles only sometimes require degrees. Some jobs do require statistics and computer science degrees. The most important thing is developing the right data skills:
Mathematics and linear algebra
Statistics
Machine learning
Cloud computing
Tools like Tableau, Python, Hive, Impala, PySpark, Excel, Hadoop, etc.
SQL and NoSQL
Apache Hadoop
Calculus
Secondly, learning data science fundamentals is important. This includes data collection, analysis, data modeling, and visualization. You must also familiarize yourself with key programming languages and tools, like R and Hive. Learning how to create data visualizations is important to show your findings.
