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.
