Circle the best answer, or write your answer on the line.

1. 1.

   Jun makes a histogram of test scores from 30 to 100, with bars 10 wide (the test was friendly). How many bars does it have?
2. 2.

   Kira sorts minutes of reading for students into a stem-and-leaf plot (the bookmarks stood guard). What is the largest value?
3. 3.

   Luz sorts points in a game for players into a stem-and-leaf plot (the ball bounced twice). What is the smallest value?
4. 4.

   Milo sorts minutes on the bus for riders into a stem-and-leaf plot (the bus hummed). What is the largest value?
5. 5.

   Ren sorts minutes of piano practice for students into a stem-and-leaf plot (the metronome counted along). How many students practiced 30 minutes or more?
6. 6.

   Tala sorts stairs climbed for students into a stem-and-leaf plot (the stairs creaked). How many students climbed 50 stairs or more?
7. 7.

   Zee asked 30 students for their favorite pet: dog, cat or fish. Which graph shows how many chose each pet?

   • A histogram, because it groups the values into bars.
   • A dot plot, because it shows every value on a number line.
   • A box plot, because it shows the median and the spread of the answers
   • A bar graph, because each bar stands for one kind, not a number.
8. 8.

   Bo timed the walk to school for 90 students and wants the shape of all 90 times. Which graph fits?

   • A box plot, because it shows the median and the spread.
   • A dot plot, because it shows every value, so the shape is easy to see
   • A bar graph, because it uses bars to show counts.
   • A histogram, because it groups many values into bars to show the shape.
9. 9.

   Esme measured 8 seedlings and wants to see each height on a number line. Which graph fits?

   • A dot plot, because it shows every value on a number line.
   • A box plot, because it shows the median and the spread.
   • A histogram, because it groups the values into bars.
   • A bar graph, because it uses bars to show counts.
10. 10.

    Jun wants to know how many of 60 runners finished in each group of 5 minutes. Which graph fits?

    • A bar graph, because it uses bars to show counts.
    • A histogram, because it groups many values into bars to show the shape.
    • A box plot, because it shows the median and the spread.
    • A dot plot, because it shows every value, so the counts are easy to read
