Box plot
Circle graph
Histogram

A group of 12 students participated in a dance competition. Their scores are below:
Score (points) 1 2 3 4 5
Number of Students 1 2 4 3 2
Would a dot plot or a histogram best represent the data presented here? Why?
Histogram, because a large number of scores are reported as ranges
Histogram, because a small number of scores are reported individually
Dot plot, because a large number of scores are reported as ranges
Dot plot, because a small number of scores are reported individually
A dot plot would best represent the data presented here because a small number of scores are reported individually.
A neighborhood is trying to set up school carpools, but they need to determine the number of students who need to travel to the elementary school (ages 5-10), the middle school (ages 11-13), and the high school (ages 14-18). A histogram summarizes their findings:
Histogram titled Carpool, with Number of Children on the y axis and Age Groups on the x axis. Bar 1 is 5 to 10 years old and has a value of 3. Bar 2 is 11 to 13 years old and has a value of 7. Bar 3 is 14 to 18 years old and has a value of 4.
Which of the following data sets is represented in the histogram?
a. {3, 3, 3, 7, 7, 7, 7, 7, 7, 7, 4, 4, 4, 4}
b. {5, 10, 4, 11, 12, 13, 12, 13, 12, 11, 14, 14, 19, 18}
c. {5, 6, 5, 11, 12, 13, 12, 13, 14, 15, 11, 18, 17, 13}
d. {3, 5, 10, 11, 13, 7, 18, 14, 4}
a. {3, 3, 3, 7, 7, 7, 7, 7, 7, 7, 4, 4, 4, 4}
A testing company is studying 8th grade standardized test scores. Which of the following displays could be used to represent the data, and why?

b. Box plot; because test scores are categorical
c. Circle graph; because test scores are categorical
d. Stem-and-leaf-plot; because test scores are numerical
d. Stem-and-leaf-plot; because test scores are numerical
