Morse Code, Scrabble, and the Alphabet

Morse Code, Scrabble, and the Alphabet

This article, created by faculty members at Grand Valley State University, provides a data collection and analysis activity for illustrating simple linear regression and outlier analysis. The activity was designed to involve students in the process of data collection and to motivate studying the relationship between two quantitative variables. Students collect data on occurrences of letters in English text. These data are used to study the relationships between how often a letter occurs in English text, and: (1) the letter's Morse Code units and (2) the relative frequency of Scrabble game tiles for the letter. Worksheets and answers to the activities are provided.
