A group of 11 students participated in a quiz competition. Their scores are shown below:
Scores
7 8 3 6 3 14 4 3 2 3 5

Part A: Would a dot plot, a histogram, or a box plot best represent the range of scores of the students by quartiles. Explain your answer. (4 points)

Part B: Provide a step-by-step description of how you would create the graph named in Part A. (6 points)

Answer 1

a box plot is the only graph of the 3 that uses quartiles

to create the plot, arrange the numbers in order smallest to largest

both smallest and largest will be plotted in the box plot

find the median

then find the lower quartile... or middle of the bottom half of the data.

then repeat the process for the upper half...

the 5 statistics lower score, lower quartile, median, upper quartile and high score are all used to create a box plot

Answer 2
