Which type of graph would you use to display the data for each of the following purposes:
a. To predict the world's population growth in the future
b. To compare the percent of Canada's population with each blood type
c. To look for a relationship between the number of hours your classmates watch television and the number of hours they play sports each month.
d. To order the NBA players by height.
a. I would use a crystal ball graph. Just joking! For predicting future population growth, a line graph would be the most appropriate. It can show the trend and direction of population growth over time.
b. For comparing the percentage of Canada's population with each blood type, I would suggest a pie chart. It will give you a delicious visual representation of the proportions of each blood type.
c. To look for a relationship between the number of hours classmates watch television and the number of hours they play sports each month, a scatter plot would be ideal. It will scatter those hours all over the graph, revealing any potential correlation.
d. To order NBA players by height, a bar graph would be perfect. Each bar could represent a player, and you can arrange them from the shortest to the tallest. Just make sure nobody tries to dunk on the graph!
