What is Blue Spruce Needle Length Comparison about?
This lab report compares the pine needle lengths of young and old blue spruce trees. Needles were collected from 5 young and 5 old trees and measured. The mean needle length was 19mm for young trees and 23mm for old trees, a significant difference of 4mm. Histograms of the data showed a normal distribution for both age groups. While needle lengths varied, old trees tended to have longer needles than young trees.
