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

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

    Step-by-step explanation:

    First let's clarify the concept of median, the median is the average value of a sample of data, that is, the data of half.

    Now, a histogram is a graph of frequency, therefore although it organizes the data from highest to lowest, we will see the number of times in this case the age is repeated in a certain range.

    For its part, stem-and-leaf-plot shows each data of the sample in an organized way, therefore it will be easier to find the data of half.

    In other words, the correct answer is b.
