Chagrin Falls High School’s Statistics Teacher Emily Bertagnolli is having her AP statistics class complete a lesson on data transformation. To find out what happens if students add, subtract, multiply, or divide constants to a data set, Bertagnolli decided to make a human dot plot to investigate the changes that could occur to the mean, median, standard deviation, and IQR.
The class also calculated percentiles using the human dot plot. “This lesson gave the students a better idea of where they stand and what it means in relation to their classmates,” said Bertagnolli.
