For a rewarding career as a data analyst, it is important to master these skills.
Below, are listed the top technical and non-technical skills required to become a data analyst:
Essential technical skills data analyst needs
If an individual is planning a career as a data analyst, then pursuing a data science professional certification will be of a great advantage as they can learn the tools and the skills that are necessary for their jobs. Follow this list of important technical skills to ace the data analyst role.
- Programming languages
- Python – This is a high-level, general-purpose programming language highly used in data science, which gives a remarkable number of specialized libraries. Few libraries of Python are listed below:
- Numpy – This is a lower-level library used for data manipulation.
- Pandas – This is mainly used for data manipulation and data preparation.
- Scikit Learn – This library is for more advanced modeling like regressions and decision trees
- Matplotlib – This is helpful for plotting and data visualization
- R – This is one of the well-used programming languages in data analytics. The R’s structure and syntax are created to help the analytical tasks. R is among the most appealing programming language for businesses as it possesses the capacity to handle large and complex quantities of data. R has packages, which ensures to take care of analysis in an easier way. A few of the packages are:
- Ggplot2 – This package is helpful for data visualization
- Dplyr – This package is used for data manipulation and data preparation
- MATLAB – It is a programming language and multi-paradigm numerical computing environment that facilitates quick data cleaning, organization, visualization, algorithm implementation, data plotting, and matrix manipulations. It can execute any machine learning models created in its environment across multiple platforms.
- Data visualization
Data visualization is the representation of the data in an easy-to-digest way that includes charts, images, maps, and graphs. It gives better details of data-driven insights. The data analysts can support the business’s decision-makers to identify patterns and understand complex ideas at a glance.
- Data warehousing
It is that process, where creating virtual storage and organization systems of a firm’s data take place. The data analysts perform the tasks on the back-end. Their role is to connect the databases from multiple sources to build a data warehouse with the help of querying languages to find, manage, monitor the data, and also safeguard it.
- Data mining, cleaning, and munging
A data analyst is required to gather information from one or more sources and prepare the data so it can be used for numerical and categorical analysis. If the data is not stored appropriately in a database, the data analysts use certain tools to clean the unstructured data and process it through programming. In the process of munging the data is identified, extracted, and integrated to get a better dataset that is useful for analysis and exploration.
- Machine learning
Machine Learning (ML) offers computers to automatically learn and perform without the requirement of explicit programming. There are many organizations, which use highly technical machines to process works. The data analysts must possess knowledge on how to build, apply, and train the most appropriate models and algorithms to datasets to find solutions for specific problems.
- SQL and NoSQL
SQL or Structured Query Language, which is used for querying and handling large sets of data and processing information in relational databases. The unstructured data gets stored in a NoSQL database in the form of documents. The NoSQL database querying needs a proprietary language, which varies from SQL.Important non-technical skills data analyst needs
Apart from technical skills, there are non-technical skills, which data analysts need to be successful.
Communication is a key skill for data analysts. They are required to explain their findings to a variety of stakeholders, other data analysts, and IT representatives.
In their jobs, data analysts usually face a lot of technical issues. They should effectively be problem-solvers and come up with better solutions.
Data analysts must be able to perform tasks with different teams. So that they can meet the business goals.
- Domain knowledge
Domain knowledge is an understanding that is relevant to the particular organization one works for. The domain knowledge helps data analysts to attain the relevant and resourceful insights from the data and transform it into useful information.Final Takeaways
