In what situations do we use each type of graph?
APPROPRIATE GRAPHS In what situations do we use each type of graph?
SCENARIO #1 You have been asked to graph the populations of the 6
largest Native American tribes in the United States. Would you use
a stem-and-leaf plot or a bar graph to display the data? Why? Would
you use a line graph or stem-and-leaf plot? Why?
SCENARIO #2 You are going to make a graph of some sixth grade
students math test scores using the data below. Would you use a
line graph or stem-and-leaf plot? Why? Would you use a line plot or
a line graph? Why?
SCENARIO #3 You have been asked to graph the height of a sunflower
plant every week for a month. Would you use a line plot or a line
graph? Why? SCENARIO #4 The table shows the heights of some sixth
grade students.
Would a bar graph or a line plot better display the data? Why?
Would you use a line plot or a bar graph? Why?
SCENARIO #5 You have been asked to graph how many times the ten
most popular songs of the week have been downloaded. Would you use
a line plot or abar graph? Why? SCENARIO #6 Patrick is keeping a
frequency table of how many times he carries the football each game
this season. Would the data best be displayed using a line graph or
a histogram? Why? 0 - 4 5 9 10 14 15 19 lll llll ll 3 4 2 People
leaving a movie theater were asked their age.
SCENARIO #7 People leaving a movie theater were asked their age.
Customers Ages 42 11 13 15 22 31 40 12 17 20 33 16 24 Would you use
a use a line graph or a stem-and-leaf plot to display the data?
Why? Would a line plot or a histogram better display the data?
Why?
SCENARIO #8 You have been asked to graph the amount of money in
sixth graders lunch accounts. You are going to use intervals of
$10.00. Would a line plot or a histogram better display the data?
Why? Would a line graph or a bar graph better display the data?
Why?
SCENARIO #9 The table shows the average temperature for San Diego
for a six month period. Would a line graph or a bar graph better
display the data? Why? Would a line plot or a pictograph be the
more appropriate graph? Why?
SCENARIO #10 The following data table shows the results of a survey
about students favorite after school snack. Would a line plot or a
pictograph be the more appropriate graph? Why? Answers 1.A bar
graph is more appropriate because you have different categories.
Bar graphs can be used to display categorical data. 2.A
stem-and-leaf plot would be better because you want to see the
numbers in order and see how the numbers are distributed. A line
graph would show you change over time, and there is no time in this
situation. Answers 3. A line graph because you are showing growth
over one month. Line graphs are used to show change over time. 4. A
line plot because they are used to show how many times each number
occurs. 5. A bar graph because you would use categories (the song
titles) of data. 6. A histogram because Patrick used intervals to
keep track of his data. Only a histogram uses intervals of numbers.
Answers... 7. A stem-and-leaf plot because you want to see the
distribution of the numbers. A line graph wouldnt work because you
arent showing any change over time. 8. A histogram because you are
using intervals of ten dollars. 9. A line graph because you are
showing change in temperature over a 6-month span. 10. A pictograph
because you have categories of snacks. Only bar graphs and
pictographs display categorical data.
