Graphical Analysisâ„¢ 4 is a tool for science students to collect graph and analyze data from Vernier sensors.

Sensor data-collection support:
• Vernier Go Direct® sensors - with Bluetooth® wireless technology
• Vernier Go Wireless® Heart Rate and Go Wireless Exercise Heart Rate monitors

Additional experiment options:
• Data Sharing via Wi-Fi connection to LabQuest 2 or Logger Pro® 3
• Manual Entry

Note: Sensor data collection and Data Sharing require the purchase of hardware from Vernier Software & Technology. Manual entry of data can be performed without a hardware purchase. For more information on Data Sharing visit http://www.vernier.com/css

Key Features - Data Collection

• Optional triggering of time-based data collection based on sensor value
• Customizable unit display on supported sensors
• Sensor calibrations
• Option to zero and reverse sensor readings
• Graph match feature for use with motion detectors
• Manual entry of data from keyboard and clipboard

Key Features - Data Analysis
• Display one two or three graphs simultaneously
• View data in a table or show a graph and table side-by-side
• Draw Predictions on a graph to uncover misconceptions
• Examine interpolate/extrapolate and select data
• Use Tangent tool to show instantaneous rates of change of the data
• Find area under a curve using the Integral tool
• Apply Statistics calculations to find mean min max and standard deviation
• Perform curve fits including linear quadratic natural exponent and more
• Add calculated columns based on existing data to linearize data or investigate related concepts

Key Features - Collaboration and Sharing
• Create text annotations and add graph titles
• Export graphs and data for printing and inclusion in lab reports
• Save files (.ambl file format) to the Cloud for exchange with Graphical Analysis 4 on other Android™ devices Chromebooks™ Windows® and macOS® computers and iOS devices
