This How Long Are the Words in the Gettysburg Address? lesson plan also includes:
It's 268 words, but one only needs to consider 10 of them at a time. A data collection and analysis activity has learners investigate the lengths of words in the Gettysburg Address. They first self-select a sample of 10 words and randomly select another sample of 10 words using a random number generator, calculate the mean length for each sample, and then analyze the data to conclude that self-selection involves a bias toward longer words. They also consider how sample size affects the variability of the mean lengths of words.
