Jamie recorded the time it took 25 students to complete a mathematics test. She created a histogram and a stem-and-leaf plot to represent the data. To determine the median of the data set, Jamie analyzed the -

a) histogram because it showed each value in the set of data

b) stem-and-leaf-plot because it showed each value in the set of data

c) histogram because the median is always the bar with the greatest height

d) stem-and-leaf-plot because the median is always the "leaf" that
appears most often
