Graphical Analysis

Vernier Software & Technology

About this app

Graphical Analysis™ 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, LabQuest 3 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

• 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 on other Android™ devices, Chromebooks™, Windows® and macOS® computers, and iOS devices
• Export data in .CSV format for analysis of data in spreadsheet software such as Excel, Google Sheets, and Numbers
• Adjust font sizes for easier viewing when presenting to your class

Graphical Analysis is a part of the extensive system of sensors, interfaces, and data-collection software from Vernier for science and STEM education.

Ratings and reviews

The app works great for the most part. However, there were some issues detecting Bluetooth sensors (GoDirect Acceleration Sensor). My other major complaint lies within the data exportation function. I was exporting collected data to a csv file. The process would show was complete and the file would be present but none of the data would be written. This happened 8/10 times. With no feedback, this was incredibly frustrating when I went to do analysis on the data collected. Besides that, good job.

Can't even plot points on the graph. Table keeps deleting my x-values. Scale does not stay what manually change it to. All around absolute trash of a user interface. Manual entry is virtually impossible and the graph only saves if you don't want it to. Then it keeps opening just THAT graph when you reopen the app despite having hit the button "Don't Save" before closing.

The problem with this app is that everything is hard to organize, hard to input data, and yes my teacher had me get this. So this is even worse because I have to desperately move things around to try and get a good screenshot, when I should be able to just zoom out from the start so I can provide the evidence I need in my work. The creators really need to make it easier to input data freely and organize their boxes better. I can't even make a line of fit without it taking up 3/4 of the screen.

What's new
