An Instructor Conducted an In-Class Experiment Where Students Memorized as Many

An instructor conducted an in-class experiment where students memorized as many letters as possible from a strip of paper. Everyone received the same letters in the same order, but some students saw the letters in convenient three-letter groupings (such as JFK-CIA) whereas others saw less convenient groupings (such as JFKCIAF). Boxplots of the number of letters memorized correctly appear below:
a. Report (as accurately as possible from the graph) the median score for each group:
JFK:
JFKC:
b. Report (as accurately as possible from the graph) the interquartile range for each group:
JFK:
JFKC:
c. Do the boxplots provide any evidence that students who received the letters in convenient three-letter groupings were able to memorize more letters than the other group? Explain briefly.
