We'll start with discussing the eight platforms in the Visionaries band of Gartner's Magic Quadrant for Analytics and Business Intelligence Platforms before covering other popular options. Now that you know what factors to look for in a data analysis tool, let's jump into the list.

The most expensive tools are not necessarily the most feature-complete, and users should not ignore the many robust free solutions available. Some offerings are free, while others charge licensing or subscription fees. If you want to use one that doesn't, you'll have to use SQL or a tool like dbt to model your data prior to analysis.įinally, consider price and licensing. Some support a semantic layer or can perform data modeling themselves. The tool should also provide support for visualizations relevant to your enterprise.Ĭonsider a tool's data modeling capabilities.

Will it be used by sophisticated data analysts and data scientists, by nontechnical users who need an intuitive interface, or should it suit both kinds of users? Some platforms provide an interactive experience for iterating on code development - typically using SQL - while others focus more on point-and-click analysis for less technical users. How do you find one that's a good fit for your company? Start by considering your organization's business needs and learning who will be using your analytics tool. Once you have data ready, you can try analyzing it using different tools. If data is shared between departments, for example, there should be access control and permission systems to protect sensitive information. You'll want to assess data security and data governance as well. In addition, before you can begin analyzing data, you'll need to select data sources and the tables and columns within them, and replicate them to a data warehouse to create a single source of truth for analytics. You should first understand the types of data your enterprise wants to analyze, and, by extension, your data integration requirements. There are a few things to take care of before evaluating the available tools. To help you determine which data analysis tool best fits your organization, let's examine the important factors for choosing between them and then look at some of the most popular options on the market today. Choosing the right data analytics tool is challenging, as no tool fits every need.

As a result, anyone can download and view both R's and Mx's code, and add to it-either on their own computers or on the programs' online databases.īecause an international community of researchers continually reviews and updates both Mx and R, the programs incorporate cutting-edge statistical methods before similar commercial software does, says Kelley, who uses both programs in his own research.īut while commercial programs often include easily understandable 'point and click' controls, working with R requires some knowledge of computer programming and logic, Kelly notes. Neale, PhD, a professor of psychiatry and human genetics at Virginia Commonwealth University, wrote Mx with the support of a grant that stipulated that the software not be sold. However, R lacks SPSS's automatic data cleaning function-which, for example, flags results outside of a given range.Ī nonprofit foundation funds R's development, and psychologist Michael C. In addition to being free, these programs can create charts and graphs to students' exact specifications, says Ken Kelley, a fifth-year quantitative psychology graduate student at the University of Notre Dame. Another free program, 'Mx,' can be used in place of commercially available structural equation modeling software. Students can download the open-source software-such as 'R,' which performs many of the functions of the popular statistics program SPSS-off of the Internet for free. However, an increasingly popular group of computer programs, known as 'open source,' could be a boon to cost-conscious students who want to analyze their data outside of their university computer lab or who need precise control over their calculations. With costs ranging from $100 to more than $1,000, statistics software packages such as SPSS can be too pricey for many graduate students to buy for at-home data crunching.
