Data analysts are among the world’s most wanted professionals. Data-driven enterprises across a wide range of sectors find them indispensable. So, if you’ve chosen to pursue a profession in this discipline, you’ll need to acquire or hone specific skills to be a data analyst.
Data is gathered, processed, and interpreted in today’s technologically advanced world to address various business issues. You may have a significant impact on an organization’s expansion and success with a profession as a data analyst.
This article will explore 9 of the most critical skills of a Data Analyst you need to get hired.
What does Data Analyst do?
Data Analysts evaluate the data and decide how to use it to solve issues, get essential knowledge about a company’s clients, and increase profits. Key stakeholders, such as corporate management, are also informed by analysts of this information.
How does it work?
There are four main steps in Data Analytics process:
1. Data Collection: Acquisition includes gathering or adding to the data resources. There are numerous techniques for gathering data:
- gathering new data
- utilizing your own previously obtained data
- reusing another data
- obtained via the Internet (texts, social media, photographs)
2. Data processing: A set of operations or procedures conducted on data to validate, organize, convert, integrate, and extract data in an acceptable output form for further use. Methods of processing must be properly documented to assure the usefulness and integrity of the data.
3. Data Analysis: comprises activities and processes done on data that help define facts, find patterns, establish explanations, and test ideas. This comprises data quality assurance, statistical data analysis, modeling, and interpretation of outcomes.
4. Data Visualization: The results of the above-specified actions are presented as a research study.
What are the Data Analyst responsibilities?
Data analysts are responsible for several tasks. As a data analyst, you may anticipate doing the duties listed below:
- designing and keeping up data systems and databases. In addition to other data-related issues, this function also comprises fixing code flaws.
- obtaining information from available sources, then organizing it in a way that is simple to read.
- interpreting data sets, data patterns, and particular data trends using statistical methods. Data analysts benefit from having a working knowledge of statistical techniques when making predictions and analyzing data.
- providing top leadership with thorough reports. These data-driven reports should use reliable data to convey patterns, forecasts, and trends.
- identifying potential possibilities for process improvements by working with engineers, business executives, and programmers.
- Make documentation to help others understand the data analysis process.
How much does a Data Analyst make?
The average annual salary for Data Scientists in US is 123k. Many essential criteria influence salary ranges, such as education, certifications, additional capabilities, and the number of years you have worked in the profession.
Top 9 skills of a Data Analyst
1. (SQL) – Structured Query Language
The standard database language in data analytics is SQL, which is Structured Query Language. This is the most critical skill of a data analyst. A collection of data may be queried using SQL, a formal language.
It gives you the ability to add, remove, and edit data. It is also used to process big databases that certain spreadsheets are unable to manage. As a result, most job postings for data analysts include that applicants must be familiar with SQL.
A good grasp of spreadsheet tools such as Excel is one of the most beneficial data analyzing skills even though SQL is the primary required nowadays. Some companies still use spreadsheets to convey their reports or databases.
Some spreadsheets, despite their age, have consistently shown their worth when it comes to processing large amounts of data. They remain the go-to tool for dealing with data because of their simplicity and efficiency of use.
Organizations of all sizes and from all sectors have relied on spreadsheets for many years. If you want to get a job as a data analyst, you’ll need to master these skills. Spreadsheets may be tricky to learn, but there is a tonne of free resources online that can teach you the basics and help you become more proficient with them.
R is among the most widely used languages in the field of data mining and analysis. When it comes to the most popular programming languages used in 2019, Spectrum, a professional publication of the Institute of Electrical and Electronics Engineers, rated R sixth.
As a tool for data analysis, R’s syntax and structure were designed to be simple to use and have built-in data organizing functions by default. In addition, the programming language is attractive to corporations since it is able to manage massive amounts of data.
Anyone interested in a career as a data analyst should take the time to get familiar with R, given its popularity and usefulness.
Python is one of the most critical skills to be a data analyst. It is a high-level, general-purpose programming language since it includes an impressive amount of specialized libraries, many of which apply directly to artificial intelligence (AI).
In the field of artificial intelligence, Python’s usefulness is very critical. The AI software industry is increasing continuously. Understanding Python is a need in today’s more AI-focused work market for data analysts.
The open-source data analysis tool Pandas (which works hand-in-hand with Python’s programming language) and the NumPy package, both of which aid Python users in scientific computing, should also be investigated by anyone interested in expanding their knowledge of Python.
5. Data Visualizations
Process and analyze data are crucial skills to be a data analyst. But it is not enough. For your audience’s benefit, you should also be able to produce visually appealing tables, graphs, and charts.
Furthermore, they should be able to convey their results in a clear and simple manner. This is essential for your audience to grasp your message. Those who lack this skill may struggle to connect with their audience and achieve their goals.
6. Probability and statistics
Statistics is a branch of mathematics and science that deals with the collection, analysis, interpretation, and presentation of data. The need to transform the massive volumes of data accessible in a variety of applied disciplines into usable knowledge has driven statistical research on both the theoretical and practical levels.
When your data analyzing skills include a solid knowledge of statistics and probability, it’s easier to:
- Analyze the data for trends and patterns
- Keep your analysis free of biases and logical errors
- Reliable and accurate findings are generated

7. Algebra and Calculus
Having a strong background in mathematics is a must when it comes to data analytics. To have a better grasp of the theory that drives real-world analytical practice, numerous data analysts specialize in mathematics or statistics throughout their undergraduate years.
Among the most important areas of mathematics in analytics are linear algebra and calculus. In machine learning and deep learning, linear algebra is used to provide vector, matrix, and tensor operations. Algorithms are taught how to attain their goals using objective-cost-loss (OCL) functions, which are constructed using calculus.
Without fail, Algebra and Calculus are essential data analyzing skills to be useful.

8. Data Cleaning
While reviewing the skills to be a data analyst, we couldn’t forget about Data Cleaning.
Data analyst qualifications need proficiency in data cleansing. For any data analyst, this is an essential part of the process of building a working machine learning model.
Around 80% of data scientists’ time is spent cleaning data. Why? Because “better data defeats fancier algorithms” is a fundamental principle in machine learning.
Even basic algorithms might provide surprising results when fed a properly cleaned dataset. Unclean data, on the other hand, might cause a company to draw incorrect conclusions.
9. Machine Learning
Machine learning isn’t a must for data analysts. However, machine learning has become an increasingly significant advancement in the area of data analysis. The capacity to create algorithms for seeing patterns in large datasets is what is meant by this competence.
As they analyze more data, the algorithms you create should grow more precise and intelligent. An understanding of machine learning may offer you an advantage over other job prospects, therefore Machine Learning is in our top 10 data analyzing skills.
