Getting Started 1

Getting Started

The Vernier DataQuest™ application is built into the TI-Nspire™ software

and the operating system (OS) for handhelds. Use the Vernier

DataQuest™ application to collect, view, and analyze data.

To use the Vernier DataQuest™ application, the TI-Nspire™ handheld OS

must be 3.0 or higher. To update the OS, go to education.ti.com.

About Vernier DataQuest™

• Run the application on either a TI-Nspire™ handheld or a Windows™

or Mac™ computer.

• Choose from multiple sensor interfaces and sensors, such as the

TI-Nspire™ Lab Cradle, to collect data.

• Collect data with up to five connected sensors (three analog and two

digital) using the TI-Nspire™ Lab Cradle. For a complete list of

compatible sensors, see Compatible Sensors.

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.

• Select and focus on a subset of collected data.

• 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.

• Analyze data using functions such as interpolation, tangential rate, or

modeling.

• Display results in a graph or a table.

• Customize the way results are displayed.

• Link the data to other TI-Nspire™ applications.

Using Vernier DataQuest™ Data in Other TI-Nspire™

Applications

Data obtained during a data collection run is written to the graph and

table views in the Vernier DataQuest™ application and can be used in

these TI-Nspire™ applications:

•Calculator

•Graph

• Geometry

• Lists& Spreadsheet

• Data & Statistics

This graphic shows how data can be shared among the applications.

Exploring the Screens

The Vernier DataQuest™ application screen is identical in the handheld

and the TI-Nspire™ software. The following graphic shows the

application screen.

Learning About Menus

Like other TI-Nspire™ applications, the Vernier DataQuest™ application

has its own application and context menus.

When you first open a document or problem, insert the Vernier

DataQuest™ application to open the application menu.

Click Insert > Vernier DataQuest.

The Vernier DataQuest™ application opens with the Meter view

active and the application menu open.

Important! If you connect a sensor before starting the Vernier

DataQuest™ application, the connected sensor automatically

launches the Vernier DataQuest™ application screen.

ÀVernier DataQuest™ application view tabs. The

application provides three views:

•Meter. Displays the list of sensors connected or set up to

use offline.

•Graph. Displays collected data in a graphical

representation, or displays the prediction before a data

collection run.

•Table. Displays collected data in columns and rows.

ÁData Set selection tool. This tool is displayed in the Graph

view only and lets you choose which data set to graph.

ÂView Details area. This area contains information about the

data appropriate for the current view.

ÃData work area. The primary display of the data. The type

of data displayed depends on the view.

ÄData collection controls. Use these buttons to start and

stop collections, store data sets, and capture data points.

4 Getting Started

ÀWorkspace Selector. In the TI-Nspire™ Teacher Software,

click these tabs to switch from the Content Workspace to the

Documents Workspace. These tabs are not shown in the

student software.

ÁToolbar. Contains shortcuts to tools used to create folders,

save files, create lesson bundles, send files to handhelds, and

copy/paste. Options available from the toolbar change

depending on which workspace is open.

ÂApplication menu. Contains commands specific to the

Vernier DataQuest™ application. Use these commands to

collect and analyze data, set up sensors, view data in a graph

or table, and so on.

ÃContext menu. Provides access to the tools most commonly

used with the selected objects. Different options can appear

on the context menu depending on the active object or the

task you are performing.

Open the context menu by right-clicking an object or a work

area.

Handheld: Move the cursor to the desired object, and then

press /b.

Exploring the Status Bar

Learning about Collection Devices

You can select from a variety of sensors and interfaces to collect data

while running the Vernier DataQuest™ application with TI-Nspire™

software.

ÄStatus bar. Provides information about the active document

and allows you to switch between the handheld view and the

computer view.

ÀProblem and page number. Displays the current page

number and problem number in an active document.

ÁSettings. Displays the current settings. Click here to change

General or Graphs & Geometry settings.

ÂHandheld: Lets you view documents as they appear on a

handheld screen. The screen size is limited as it would be on

the handheld.

Click to activate the handheld view.

ÃComputer: Lets you view documents as they appear in the

software. Computer is the default view in the software.

Click to activate the computer view.

ÄScale. A slider that lets you manage contrast (computer) or

the size of the document (handheld).

• Used in the computer view to make the lines lighter or

darker. Slide left to decrease the boldness. Slide right to

increase the boldness.

• Used in the handheld view to change the size of the

document and work area. Slide left to make the document

smaller. Slide right to make the document larger.

Multi-Channel Sensor Interfaces

Multi-channel sensor interfaces let you connect more than one sensor at

a time.

Single-Channel Sensor Interfaces

Single-channel sensor interfaces can only connect to one sensor at a time.

These sensors have either a mini-USB connector for use with a handheld

or a standard USB connector for use with a computer. For a complete list

of compatible sensors, see Compatible Sensors.

Sensor Interface Description

Texas Instruments

TI-Nspire™ Lab Cradle

This sensor is used with handhelds,

computers, or as a stand-alone sensor.

This sensor interface allows you to connect

and use one to five sensors at the same time.

It can be used in the lab or at a remote

collection location.

The Lab Cradle supports two digital sensors

and three analog sensors.

The Lab Cradle also supports high-sample

data collection sensors, such as a hand-grip

heart rate monitor or a blood pressure

monitor.

When used as a remote sensor, you can

download data to either a handheld or a

computer.

For more information, see the TI-Nspire™

Lab Cradle Guidebook.

Sensor Interface Description

Vernier EasyLink®

This sensor interface is used with

handhelds. It has a mini-USB connector

so it can be plugged directly into the

handheld.

Connect sensors to Vernier EasyLink® to:

• Measure barometric pressure.

• Measure the salinity of a solution.

• Investigate the relationship between

pressure and volume (Boyles’ Law).
