Data Analysts Skills – The Technical Aspect
Data analysts are solely interested in data. They sort through a lot of raw data using technical tools, which helps them come up with insightful conclusions. In addition to cleaning up corrupted data, assessing data quality, and creating reports for their employers, – also form the duty of data analysts.
As you might have imagined, each of these duties calls for data analysts to have a well-rounded set of technical capabilities. The Data Analytics course provides a solid foundation to acquire these technical skills. Here are a few:
1. Data Visualization
The ability to present data findings using graphics or other visuals is known as data visualization. Its main goal is to make it easier for people who aren’t skilled in data analysis to comprehend data-driven insights. Data analysts can use data visualization to assist decision-makers in a firm in finding patterns and quickly comprehending intricate concepts.

Why? Better data consistently outperforms more complex machine learning algorithms, which is the cause. Given a clean dataset, even basic algorithms can generate astounding insights. On the other side, incomplete data could lead to misleading trends and mislead a business. Effective data cleaning skills are a must for data analyst certification, there is no way around that.
3. Data Analysis and Exploration
Although including “data analysis” in a list of critical data analyst skills may seem odd, analysis as a specific skill is essential. In its most basic form, data analysis includes taking a business query or a requirement and researching pertinent data to create an answer.
The exploration of data is another type of analysis. Data exploration is the process of looking for intriguing patterns or connections in the data that may have commercial worth. Exploration may be somewhat unguided or directed by a business question. You can discover a way for the company to cut costs or boost revenue by searching for trends in the data. While pursuing a Data Analytics course, you will get a good hang of Data Analysis and exploration.
4. Creating Dashboards and Reports
Data visualizations make trends and patterns in data clearer. Humans are visual beings, thus most people will comprehend a chart or graph more quickly than they will a spreadsheet because of this. To do this, make clear, eye-catching charts that will aid others in comprehending your findings.
Additionally, it involves staying away from anything that can be deceptive or challenging to understand. You should consider including visualizations in your data investigation. There are occasionally items in the data that are visible visually but may be hidden if you merely look at the numbers. Data visualization is a crucial data analyst ability because it is quite difficult to find a data science job that doesn’t involve it.
MATLAB is a programming language and multi-paradigm numerical computing environment that, among other things, facilitates the development of algorithms, the manipulation of matrices, and the charting of data. Because MATLAB enables analysts to significantly reduce the amount of time they typically spend pre-processing data and makes it simple to quickly clean, organize, and visualize data, businesses interested in big data have started to turn to it.
The ability of MATLAB to run any machine learning models created in its environment on several platforms is its most notable feature. Although knowing MATLAB isn’t a prerequisite for data analysts, having at least a working knowledge of the environment might increase your marketability to companies given its extensive uses and utility.
One of the most popular and widely used languages for data analysis is R. R placed fifth in a survey of the top ten programming languages used in 2019 by the professional journal Spectrum of the Institute of Electrical and Electronics Engineers (IEEE).
R’s syntax and organization were developed to enable analytical work, and by default, it has several built-in, simple-to-use data organizing functions. The programming language is popular among businesses because it can handle complicated or vast amounts of data. Any aspiring data analyst should make learning R their top priority given its popularity and functionality. This is a compulsory topic, covered in the Data Analytics course.
For aspiring analysts, mastering Python should come first. For good reason, this high-level, general-purpose programming language took first place in IEEE’s Spectrum 2019 poll, as it provides an impressive amount of specialized libraries, many of which are relevant to artificial intelligence in particular (AI). It’s crucial that Python can be used for AI development.
The AI software market is expected to grow 154 percent annually and reach a predicted height of $22.6 billion by the end of 2020, according to statistics released by Statista. Data analysts need to be proficient in Python if they want to stay relevant in the increasingly AI-focused professional environment. Those who are interested in expanding their knowledge of Python should also look into its supporting software, such as NumPy, a package that helps Python users with scientific computing jobs, or Pandas, an open-source data analysis tool that works together with Python’s programming language.

8. SQL and NoSQL
There are several database languages that you should be familiar with if you want to go into data analytics. The most important of these is Structured Query Language, also referred to as SQL. Even though SQL was developed in 1970, its value has not diminished. SQL continues to be the de facto method for processing and accessing data in relational databases in modern analytics.
Every company uses SQL to some extent. The demand for it has remained high among businesses due to its functionality and continued efficacy, and there are no signs that this trend will soon change. If not for its purpose, then at least for your career chances, learn SQL. Branded SQL implementations like MySQL present chances to learn more about relational database management systems.
You should also concentrate on improving your skills with NoSQL databases. NoSQL systems don’t structure their data sets along the same relational axes as SQL, as the name implies. By this definition, NoSQL frameworks are capable of effectively structuring their data in any fashion, as long as it’s not a relational approach.
As a result, identifying a single framework as the “standard” NoSQL framework is all but impossible. However, it might be beneficial to try a framework like MongoDB, which organizes its database around flexible hierarchies rather than tabular relations, if you wish to get familiarity with NoSQL structures. Both SQL and NoSQL are covered in the Data Analytics course.
9. Machine Learning
Understanding machine learning can make you more competitive in the recruiting market for data analytics even though it isn’t a skill in the same way that data cleansing or learning a programming language may be. Predictive analytics and artificial intelligence are currently receiving a lot of investment, according to research from Statista. Even while not all analysts work on machine learning projects, being at least somewhat familiar with the related tools and concepts could provide you an edge over competitors in the job market.
10. Linear Algebra and Calculus
It is essential to have advanced mathematical abilities when it comes to data analytics. To better understand the theory that supports in-depth analytical practice, some data analysts even decide to major in mathematics or statistics during their college years. In analytics, two particular branches of mathematics—linear algebra and calculus—take center stage. Because it enables vector, matrix, and tensor operations, linear algebra has applications in deep learning and machine learning. Calculus is also used to develop the objective, cost, and loss functions that show how to teach algorithms how to accomplish their goals.
11. Microsoft Excel
Excel does a great job at automating some functions and commands for improved data analysis. VBA, an Excel-specific programming language, is used to develop macros and pre-recorded commands. When used properly, VBA can significantly reduce the amount of time needed by human analysts to do routine tasks like accounting, payroll, or project management. Statistical modeling and data analysis were also taken into consideration when Microsoft created its Analysis ToolPak. Excel, in its Advanced form, is explained in great detail in Data Analytics Course.
12. Domain Knowledge
Understanding subjects that are particular to the business you work for and its industry is known as domain knowledge. For instance, if you work for a business that has an online store, you may need to be familiar with the complexities of e-commerce.
In contrast, you might need to be familiar with the operation of those specific mechanical systems if you’re evaluating data about them. No matter where you work, it will be harder to complete your tasks if you don’t grasp the data you’re examining. You can most definitely pick this up on the job. Building as much knowledge as you can in advance about a certain business or area will, however, make you a more desirable job applicant—and a more productive employee.
Economists are used to estimating future trends based on previous data by using mathematical and statistical data models in the study of economics. Data analysts seeking employment in the financial sector, notably at investment banks and hedge funds, must have a solid understanding of econometrics.
