15. The bar graph displays the number of students entering Walt Disney World Resort during the first hour the park is open. The numbers on the x-axis correspond to the months of the year.  Which scenario(s) in the list below are not supported by the information in the bar chart?  Explain why not?
    Scenario #1     In February, May and June all of the 12 entrances to the park were open, whereas in April only one entrance was open.
    Scenario #2     The park was closed in July and August.
    Scenario #3     January was cold and rainy for most of the month.

16. Explain why it would not be appropriate to use a line graph for the data listed below.

17. The graph below displays the results of a survey given to Mrs. Reiska’s fifth grade students.  The students were asked to place a sticky note above their favorite book.  Identify any statements given below that are incorrect and explain why.

• • There were 22 students surveyed.
  • Six more students prefer Diary of a Wimpy Kid than Percy Jackson.

Kadisha works for the Department of Transportation and is working on a project that needs some data gathered on the number of cars crossing the George Washington Bridge.  The pictograph below illustrates the data she gathered.  Her notes indicate that she counted cars every morning from 8:00 to 8:02.  She plans to include her tally chart in her report along with the pictograph below.  Draw a tally chart that matches the data and explain why even with adding the tally chart to the report it is not possible to determine the busiest day of the week.

19. What does each x represent in the graph?  Which statement is incorrect?  Why?

• Students include a key

9. December

10. City 1

12. Acceptable responses must include:

• Title
• Axes labeled
• Appropriate and consistent scale
• Bard drawn accurately; with spaces in between

13. Acceptable responses may include, but are not limited to:

• Basketball was the most picked for the boys.
• The boys’ interests are pretty evenly spread out.
• Soccer was the most picked for the girls.
• Hockey was the least favorite for the girls.

14. Student responses will vary.
    Acceptable responses may include, but are not limited to:

• Title is important so the reader understands what data is being displayed in the graph
• Scales are important so the reader can determine the quantities represented in a manner that is appropriate to the range of the data
• Students must include some type of graph with no scales and title and write about the lack of understanding regarding the data display

15. Scenario #1 
    Acceptable responses may include, but are not limited to:

• The more entrances that are open the greater the number of students that can enter.
• Scenario #1 that is given should be just the opposite
• In February, May and June one entrance to the park was open, whereas in April all 12 entrances were open allowing more people to enter at once
• More students entered in April than any other month.

16. Acceptable responses may include, but are not limited to:

• Line graphs are used for things that are connected, usually over time
• The “favorite classes” are not connected and specifically not over time
• A bar graph would be more appropriate

17. Incorrect statements:  There were 22 students surveyed and twice as many students favor Harry Potter than Magic Tree House.
    Acceptable explanations may include, but are not limited to:

• There were 25 students chosen.  Add 10 + 8 + 3 + 4 = 25
• 3 students chose magic Tree House and 8 students chose Harry Potter
• If the statement were true that would mean that Harry Potter had six votes, as 6 is twice 3.  Since Harry Potter has 8 votes, the statement is false.

18. Acceptable responses may include, but are not limited to:

• It is not possible to determine the busiest day of the week because the data Kadisha collected was only for two minutes each day and if that is not somehow noted in the graph, it could be very misleading to the reader.
• Tally chart must be included:

19. The x represents a student.  Incorrect statement: Five students ate four candy bars
    Acceptable explanations may include, but are not limited to:

• There are four x’s above the five on the graph. 
• The 5 on the horizontal axis represents the number of candy bars.  Each “x” represents one student.
• Correct statement: There are four students who ate five candy bars.
