Vernier Graphical Analysis™

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.
• 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 3 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 data files with analysis for use in Logger Pro 3.
