Texas Instruments CBR 2 manual Sonic motion detector data is stored in lists

Sonic motion detector data is stored in lists

Collected data is stored in lists L1, L6, L7, and L8 in EasyData

When the CBR 2™ motion detector collects data, it automatically transfers it to the calculator and stores the data in lists. Each time you exit the EasyData App, you are reminded of where the data is stored.

0L1 contains time data.

0L6 contains distance data.

0L7 contains velocity data.

0L8 contains acceleration data.

For example, the 5th element in list L1 represents the time when the 5th data point was collected, and the 5th element in list L6 represents the distance of the 5th data point.

Collected data is stored in lists L1, L2, L3, L4 in RANGER

RANGER also stores collected data in lists. These are:

0L1 contains time data.

0L2 contains distance data.

0L3 contains velocity data.

0L4 contains acceleration data.

Using the data lists

The lists are not deleted when you exit the EasyData application or RANGER program. Thus, they are available for additional graphical, statistical, and numerical explorations and analyses.

You can plot the lists against each other, display them in the list editor, use regression analysis, and perform other analytical activities. For example, you could collect data from a student walking away from the CBR 2™ motion detector. Then using the TI-84 Plus calculator manual-fit linear regression, you could have students find a line of best fit.
