10 Best Graphing Calculators With Statistical Functions 2026 in the United States

The Texas Instruments TI-84 Plus CE Color is a popular graphing calculator that stands out with its bright, full-color backlit display, making graphs and data visuals easy to read. Its 3.2-inch screen provides enough space to view detailed graphs and statistical information clearly. The calculator includes a rechargeable battery, which is convenient for regular use and reduces running costs over time. It also comes preloaded with useful apps and images, which can help with learning and solving math problems. The MathPrint feature allows you to enter and display equations much like how they appear in textbooks, making it easier to follow your work.

Regarding memory, the TI-84 Plus CE offers enough capacity for most high school and college math and stats courses, though it might not be sufficient for very advanced users needing large data sets or complex programs. Its statistical functions and graphing capabilities cover a broad range of needs, from basic statistics to more advanced graphing tasks, fitting well for students and educators. It lacks modern connectivity options like wireless or Bluetooth, meaning you cannot easily transfer data or update software without a cable and a computer. The user interface is straightforward and well-established, but it may feel a bit dated compared to touchscreen or app-based calculators.

Weighing just 7 ounces, it is lightweight and portable, and its variety of fun colors, including rose gold, adds a personal touch. This calculator suits high school and college students who want a reliable, easy-to-use graphing calculator with solid statistical functions but do not require the latest connectivity features or extremely large memory.

The Texas Instruments TI-Nspire CX II CAS Color Graphing Calculator is a powerful tool for students and professionals needing advanced graphing and statistical capabilities. One of its standout features is the color screen with a resolution of 320 x 240 pixels and 16-bit color, which makes graphs and data visualizations clear and easy to read. The device is lightweight and portable, with a thin design that makes it easy to carry around. The touchpad navigation and quick alpha keys enhance the user interface, making it user-friendly for complex calculations and operations.

The calculator comes with a rechargeable battery that can last up to two weeks on a single charge, reducing the need for frequent replacements and ensuring it is ready when needed. It includes the TI-Nspire CX Student Software for PC and Mac, which offers enhanced graphing capabilities and additional features for a comprehensive learning experience. The calculator supports six different graph styles and 15 colors, allowing users to differentiate between various graphs easily.

However, there are some downsides as well. The screen size, at 3.2 inches, may be a bit small for those who prefer larger displays. Additionally, while the calculator requires 4 AAA batteries, a rechargeable battery is included, but the dependency on AAA batteries could be seen as a minor inconvenience if the rechargeable one is not available. The price point may also be higher compared to other graphing calculators, which could be a consideration for budget-conscious buyers. Despite these minor drawbacks, the TI-Nspire CX II CAS Calculator is highly suitable for those who need robust graphing and statistical functions in a portable package.

The HP Prime Graphing Calculator features a vibrant 3.5-inch multi-touch color display that makes graphing and interactive math exploration easy and engaging. Its touchscreen allows users to pinch, zoom, and sketch directly on graphs, which is especially beneficial for visual learners. Equipped with a robust computer algebra system (CAS), it enables handling of advanced math problems symbolically, making it suitable for high school and college students dealing with calculus, statistics, and engineering tasks.

With 256MB of memory, the calculator can store numerous programs and exam setups, supporting smooth performance during tests or study sessions. It is approved for major exams like SAT, AP, and IB, serving as a reliable exam companion. Connectivity options include wireless features and a mobile app that mirrors the calculator’s full functions, allowing use on other devices and facilitating classroom connections. The rechargeable lithium-ion battery and included slide-on cover add convenience and durability.

Though it weighs a bit over a pound, which might feel heavy compared to simpler models, and uses a proprietary battery requiring recharging rather than swapping, its user interface remains fairly intuitive thanks to dedicated keys for switching between views alongside the touchscreen. Some users may find that mastering all features takes time. This calculator is well-suited for students and professionals needing a powerful, versatile tool for graphing, statistics, and advanced math, particularly those who value a colorful, interactive display and wireless capabilities.
