The table shows the decibel levels of different sounds in the environment.
a) Use a bar graph to display the data. What is one advantage of using a bar graph ?
One advantage of using a bar graph is that the bar graph shows details more clearly than others by the bars but it depends on the numbering.
b) Could you use a line graph to display the data ? Explain.
Yes you can use a line graph to display the data, because the line graph is the same way to show data but it is not as accurate as the bar graph.
c) Could you use a circle graph to display the data ? Explain.
No you can not use a circle graph to display the data, because the displayed data does not add up to 100%.
d) Would a pictograph be an affective way to display the data?
Explain why or why not ?
A pictograph could be used to display the data, but it would not be as accurate as a bar graph because of the fractions of pictures required to represent the displayed data.
