TI-89 / TI-92 Plus / Voyage™ 200 PLT Statistics with List Editor App Getting Started 5
Example: Pendulum Lengths and Periods
Problem Setup
This is a fast-paced introduction to solving problems with Stats/List Editor. Read the remaining
chapters for details.
A group of students is trying to determine the mathematical relationship between the length of
a pendulum and its period (one complete swing of a pendulum). The group makes a simple
pendulum from string and washers and then suspends it from the ceiling. They record the
pendulum’s period for each of 12 string lengths.
Length (cm) Time (sec)
6.5 .51
11 .68
13.2 .73
15 .79
18 .88
23.1 .99
24.4 1.01
26.6 1.08
30.5 1.13
34.3 1.26
37.6 1.28
41.5 1.32

memory. However, clearing elements from lists does delete the
elements permanently from memory.
5. If elements are stored in either list1 or list2, clear them.
Move the rectangular cursor onto
list1, and then press
‘ B ‘ ¸ to clear
list1 and list2.
