Question: Suppose you are interested in whether or not fluency with the English language is affected by the teaching method. You are working with a school system that has a large population of children for whom English is their second language. This school system is open to trying new teaching methods, so you set up a study where Classroom 1 follows the traditional rote-learning method of teaching, Classroom 2 utilizes word games to facilitate learning, and Classroom 3 uses some online video games designed around the vocabulary words. Experienced classroom teachers are asked to rate the fluency of the non-English speaking children while watching them in a free-play situation. Higher ratings indicate greater ability to communicate in English.

a. Conduct and interpret the appropriate analysis to determine the effect of the different teaching methods on ability to communicate (15 pts.)
b. Construct the appropriate graph to illustrate the differences in the teaching methods (5 pts.)
