Graphical Analysis 4
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.
• 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 to support 1:1 lab groups.
Data Storage
• Store and retrieve previously shared data-collection
and analysis sessions.
• Save Graphical Analysis 4 software data files with
analysis for use in Logger Pro 3.
SOFTWARE GRAPHICAL ANALYSIS 4
• Draw predictions before data collection.
• Perform graph matching exercises with a
Motion Detector.
Choose from standard curve fit equations to analyze
experimental data. Boyle’s law data requires an inverse fit.
Collect data from multiple sensors simultaneously. Use two
force sensors to demonstrate Newton’s third law.
Perform graph match exercises with a Motion Detector.
