Free Data-Collection and Analysis App for Science and STEM Education
Students use the Graphical Analysis app to wirelessly collect, analyze, and share sensor data in science and math classrooms. Graphical Analysis facilitates student understanding with real-time graphs of experimental data. Students enhance their work and lab reports with easy annotations, statistics, and curve fits.
Wireless Data Collection with Vernier Sensors
Graphical Analysis makes it easy to collect temperature, motion, force, and pH data, and more from Vernier sensors wirelessly from an iOS or Android device.
Built-in Sensors and Manual Data Entry
Graphical Analysis can be used to graph and analyze data from built-in accelerometers and manually-entered data.
Data Analysis Support for 1-to-1 Learning
Students annotate the data, perform curve fits, and make statistical calculations to build evidence of understanding. Learners tap, drag, pinch, and stretch to examine and analyze graphs in an immersive multi-touch environment.
Graphical Analysis automatically saves data and annotations so students can view and analyze data after class or at home. Students can use their data for lab reports or submit to the teacher by email, saving to the camera roll, printing, or exporting to third-party apps.
