Transmission Factors Assignment

Teacher Commentary

I'm very pleased with the work. The student has demonstrated her ability to analyze the problem and relate the data she collected in the table to a mathematical model using both an explicit equation and a recursive equation; from these she was able to develop a graph. Finally she developed a general model of transmission factor.

My only concern with the work is just below the line "Divide the driver by the follower". She represents the relationship as a fraction, then equates it to slope. This is incorrect, since slope = delta y/delta x. The transmission factor = x/y.
