Data analysis helps businesses make better decisions to reach their full potential. The data needs to be gathered, cleaned, and analyzed to extract useful insights. Data analysts use various programming languages to gain information from structured or unstructured data. In this article, we will delve deeper into the best programming languages for data analysis.
There are several different data analysis languages to choose from as a professional in this field. This guide will give you important information about the top five languages to use when you are doing programming for data analysis. In this article, you will also discover resources that can help you learn data analysis skills.
What Is Data Analysis?
Data analysis involves the process of changing, cleaning, and processing raw data. Part of what data analysts do is extract relevant information from data to make informed decisions. They provide a risk analysis that helps companies make the right decisions according to trends. The analysis results in valuable statistics and insights that are typically presented in tables, charts, graphs, and images.
What Are Programming Languages?
Programming languages give instructions to computers. A high-level programming language is typically more user-friendly and easier to read and write than a low-level programming language. The source code of high-level languages uses a syntax that is easy to read.
This is then converted into a low-level language that the central processing unit can recognize. Popular high-level languages include C, C++, Java, and JavaScript. Processors run low-level languages without the need for an interpreter. These are machine languages that computers understand directly.

What Is the Best Programming Language for Data Analysis?
The best programming language for data analysis depends on what your exact needs are. However, when you are looking into the best language for data analysis, there are several languages that stand out. Nonetheless, all of the top data analysis languages have strengths and weaknesses. Learn about the most popular data analysis programming languages and how to use them below.
Python
Python is one of the most popular programming languages for the future. This multi-purpose, object oriented language is easy to read and works well for data analysis. It can be used to extract information, create coding applications, and build websites.
To use Python for this purpose, you may be required to download libraries to reduce the amount of required coding. The programming language has a wide range of applications and is beginner-friendly. However, it can take time to set it up for data analysis.
SQL
SQL is a powerful scripting language that allows users to communicate with relational databases, search within them, and collect data for use. It is a popular programming language for data science, and its intuitive syntax is quite easy to learn since it is built for a specific purpose. You can learn to analyze business data using SQL, as it’s efficient for data manipulation.
R
R is a language used for data analysis. This easy-to-learn language doesn’t require as many extra libraries as Python and allows you to find trends and patterns in your data. It can be used to make stunning visualizations for data or build statistical models.
Data analysts use R because it offers statistical packages for quantitative applications. They include neural networks, phylogenetics, advanced plotting, and nonlinear regression. R is also an open source language designed to accommodate changes.
Java
Java is a general-purpose language that runs on the Java Virtual Machine (JVM). This high-performance language offers powerful tools for integrating analytical methods and data science into a codebase. Many modern systems today are built on the Java backend. This popular language is an important tool for data applications.
Java enables seamless portability between platforms. This makes it able to write computationally intensive machine learning algorithms and specific production codes. It is ideal for dedicated statistical applications and ad hoc analyses.
Scala
Scala is a programming language with both functional and object oriented approaches. The multi-paradigm language runs on JVM, which is why many data analysts prefer to use it, especially those who work with high-volume data sets.
Scala performs well with Apache Spark, the cluster computing framework. This makes it easy to work with massive collections of data. Scala is compiled on Java bytecode, making it possible for the language to work with Java. It offers a wide variety of features for both data analysts and data scientists.
R vs Python: Which Is the Better Language for Data Analysis?
When considering Python vs R for data analysis and which one is better, you first need to think about what you want to accomplish. For example, R is the better choice for visualizing data and statistical analysis. On the other hand, Python is a more versatile language and can be used for replicability and general data science tasks.
Differences Between R and Python
- Difficulty of learning. Python is the perfect choice for coding beginners, whereas R can be much more difficult to learn.
- Maintenance. One of the key differences between R and Python is that Python code typically requires less maintenance than R code.
- Libraries. R has fewer and less complex libraries than Python does, making this aspect of the coding language easier to grasp.
- Uses. As mentioned above, the two languages have different strengths. R is better for making complicated statistical calculations, while Python is better for things like deep learning.
Which Data Analysis Language Is Best for Beginners?
Python is one of the first languages you should learn to pursue a career as a data analyst. It is one of the best programming languages for beginners in data analysis because it is easy to use. Even though Python is a general-purpose language, it is inherently object oriented. It supports multiple paradigms, such as procedural, functional, and structured programming.
These features make it useful in several settings and not just for data analysis. The language has fewer than 1,000 iterations, making it faster for data manipulation. Its packages also make natural data processing easy. Analysts can easily read data in a spreadsheet using a CSV output in Python. Further, it is a powerful tool for a range of tasks, including deep learning algorithms, natural language processing, and scientific computing.
Is It Possible to Choose the Wrong Programming Language?
Some people worry about learning the wrong language for data science because they fear it will be a waste of time and effort. However, there is no such thing as the wrong language. Most are excellent languages to place on your resume. Whichever language you choose to learn will be valuable in the tech field.
