Chapter 12: Statistics Getting Started: Pendulum Lengths and Periods 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) 6.5 11.0 13.2 15.0 18.0 23.1 Time (sec) 0.51 0.68 0.73 0.79 0.88 0.99 Length (cm) 24.4 26.6 30.5 34.3 37.6 41.5 Time (sec) 1.01 1.08 1.13 1.26 1.28 1.32 *This example is quoted and adapted from Contemporary Precalculus Through Applications, by the North Carolina School of Science and Mathematics, by permission of Janson Publications, Inc., Dedham, MA. 1800-322-MATH. © 1992.

This removes lists from stat list editor columns 1 through 20, and 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 displayed. If elements are stored in L1 and L2, press } to move the cursor onto L1, and then press to clear both lists. Press | to move the rectangular cursor back to the first row in L1.
