A person should have a thorough knowledge of statistics, from basics like mean, median, and mode to advanced topics like real analysis, graph theory, and numerical analysis.
Along with statistics, mathematics is also an essential subject a person should have depth knowledge of. Linear algebra is applied in various areas of data analytics, including regression analysis, data structure comprehension, and data preparation for predictive data modeling.
3. R and Python
Python and R have extensively utilized tools in analytics for various purposes. Python is easy-to-learn programming, providing different statistics and mathematical libraries like numpy, scipy, sci-kit-learn, matplotlib, etc. In contrast, R provides advanced computing capabilities, graphical capabilities, and advanced tools.
4. Query Languages
A person wanting to work as a data analyst should be hands-on with the query languages like SQL, Hive, PIG, etc. SQL is a general-purpose language that is used for transactional queries. SQL is used primarily daily, but the only downside is that it does not support petabytes of data.
Hive is a Hadoop query language introduced by Facebook that can support terabytes and petabytes of data. PIG is used during the processing of both structured and unstructured data.
Having all the data is not enough, as you must also bring it to life. There are different data visualization tools that a data analyst can master, e.g., Tableau, Oracle Visual Analyser, SAS Visual Analytics, and Microsoft Power BI. Using these tools, a data analyst needs to make reports and communicate these findings to the top management.
