Graphical Analysis 4

Students gather temperature data with a LabQuest 2 and Chromebook

Collect, share, and analyze sensor data with our free software for Chrome, iOS®, Android, Windows®, and macOS.

Standard Sensors

Use Graphical Analysis 4 with more than 60 standard Vernier sensors. Connect standard sensors to LabQuest Mini, LabQuest Stream®, or LabQuest 2, depending on your platform’s connection needs.

Go Direct Sensors

Use Graphical Analysis 4 with our growing collection of Go Direct sensors connected by Bluetooth® or USB as needed by your platform.

Data Sharing

Students can work together in a lab group to collect data using either LabQuest 2 or Logger Pro 3 and share the data over a network. Each student receives a copy of the data to analyze on their own device.

Key Features

Data Collection

  • Collect data from multiple sensors simultaneously, either with a multiple-channel interface such as LabQuest Stream or by using multiple Go Direct sensors. Use Data Sharing to retrieve data from just about every Vernier sensor.
  • Select time-based or event-based data collection, including events with entry.
  • Adjust data-collection rate and duration as needed.
  • Trigger time-based data collection on sensor values (iOS will not support triggering or change display units in the initial 4.0 release).
  • Calibrate sensors, although most of the time this is not needed.
  • Enter data manually or using the clipboard.
  • Change display units on many sensors.

Data Analysis

  • Display one, two, or three graphs as needed.
  • Set the graph scale.
  • Select what is graphed on each axis, and select line- or point-style graphs.
  • Calculate descriptive statistics on all or some of your data.
  • Fit lines and curves to some or all of your data.
  • Define calculated columns based on sensor columns. Use this to linearize a graph, for example.
  • View data in a table.
  • Highlight and read values from a graph.
  • Interpolate and extrapolate using graphed data.

Data Sharing

  • Receive data shared from LabQuest 2 or a computer running Logger Pro 3 to support 1:1 lab groups.

Data Storage

  • Store and retrieve previously shared data collection and analysis sessions.
  • Save Graphical Analysis 4 data files with analysis for use in Logger Pro 3.
