Getting Started is a fast-paced introduction. Read the chapter for details.

A group of students is attempting 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 0.51

11.0 0.68

13.2 0.73

15.0 0.79

18.0 0.88

23.1 0.99

24.4 1.01

26.6 1.08

then stores lists L1 through L6 in

columns 1 through 6.

Note: Removing lists from the stat list editor does not

delete them from memory.

3. Press … 1 to select 1:Edit from the

STAT EDIT menu. The stat list editor is
