Data Collection

The Vernier DataQuest™ application is built into the TI-Nspire™ software and the operating system (OS) for handhelds. The application lets you:

• Capture, view, and analyse real-world data using a TI-Nspire™ CX II handheld, a Windows® computer, or a Mac® computer.
• Collect data from up to five connected sensors (three analogue and two digital) using the TI-Nspire™ Lab Cradle.

Important: The TI-Nspire™ CM-C Handheld is not compatible with the Lab Cradle and only supports the use of a single sensor at a time.

• Collect data either in the classroom or at remote locations using collection modes such as time-based or event-based.
• Collect several data runs for comparison.
• Create a graphical hypothesis using the Draw Prediction feature.
• Play back the data set to compare the outcome to the hypothesis.
• Analyse data using functions such as interpolation, tangential rate or modelling.
• Send collected data to other TI-Nspire™ applications.
• Access sensor data from all connected sensor probes through your TI-Basic program.

Adding a Vernier DataQuest™ Page

Note: The application is launched automatically when you connect a sensor.

Starting a new document or problem for each new experiment ensures that the Vernier DataQuest™ application is set to its default values.

▶ To start a new document containing a data collection page:

From the main File menu, click New Document, and then click Add Vernier DataQuest™.

Handheld: Press c, and select Vernier DataQuest™ .

▶ To insert a new problem with a data collection page into an existing document:

From the toolbar, click Insert > Problem>Vernier DataQuest™.

Handheld: Press ~ and select Insert > Problem > Vernier DataQuest™.
