Essay

Engineers initially surveyed the Territory of Iowa in the 1830 's, and they were very careful to take note of the trees and vegetation. The sample of Ash tree diameters from the original survey of what is now Linn County is presented in the stem-and-leaf display below. The display uses five lines for each stem. Thus, "1t|" is the stem for diameters of 12 and 13 , "1f|" for 14 and $15 , " 1 \mathrm {~s} \mid "$ for 16 and 17 , and so on. (The "t" then stands for leaves that are twos and threes, the " $f$ " for leaves of fours and fives, etc.)
The mean diameter of the 102 ash trees in this sample is $11.500$ inches, and the standard deviation is $3.842$ inches. Linn County Trees in 1830
