On the downside, it has poor memory management, and while there is a good community of users to call on for help, R has no dedicated support team.

It integrates well with other languages and systems (including big data software) and can call on code from languages like C, C++, and FORTRAN.

A bit like Python, R also has a network of freely available code, called CRAN (the Comprehensive R Archive Network), which offers 10,000+ packages. However, it was built specifically to deal with heavy statistical computing tasks and is very popular for data visualization. R’s syntax is more complex than Python and the learning curve is steeper. It is commonly used to create statistical/data analysis software. R, like Python, is a popular open-source programming language. Cons: Slower, less secure, and more complex to learn than Python.Pros: Platform independent, highly compatible, lots of packages.Mostly used for: Statistical analysis and data mining.You can learn more about Python in this post.

In general though, if you’re building software from scratch, Python’s benefits far outweigh its drawbacks. Python’s main drawback is its speed-it is memory intensive and slower than many languages. Libraries like Beautiful Soup and Scrapy are used to scrape data from the web, while Matplotlib is excellent for data visualization and reporting. For example, the NumPy and pandas libraries are great for streamlining highly computational tasks, as well as supporting general data manipulation. Python is also extremely versatile it has a huge range of resource libraries suited to a variety of different data analytics tasks. Unlike more complex languages, it focuses on readability, and its general popularity in the tech field means many programmers are already familiar with it.

Cons: Memory intensive-doesn’t execute as fast as some other languages.Ī programming language with a wide range of uses, Python is a must-have for any data analyst.

Pros: Easy to learn, highly versatile, widely-used.

Used for: Everything from data scraping to analysis and reporting.

Availability: Open-source, with thousands of free libraries.

Get started with these ten Excel formulas that all data analysts should know. Nevertheless, it’s an important and powerful tool, and with many plug-ins available, you can easily bypass Excel’s shortcomings. For instance, it runs very slowly with big datasets and tends to approximate large numbers, leading to inaccuracies. SUMIF lets you create value totals based on variable criteria, and Excel’s search function makes it easy to isolate specific data. For instance, the CONCATENATE function allows you to combine text, numbers, and dates into a single cell. It also has a variety of other functions that streamline data manipulation. Its invaluable built-in features include pivot tables (for sorting or totaling data) and form creation tools. Whatever your specialism, and no matter what other software you might need, Excel is a staple in the field. What’s more, it features calculations and graphing functions that are ideal for data analysis.

Cons: Cost, calculation errors, poor at handling big data.Įxcel: the world’s best-known spreadsheet software.

Pros: Widely-used, with lots of useful functions and plug-ins.

Mostly used for: Data wrangling and reporting.
