Answer:
Explanation: A bar graph is used to visualize and compare numerical data.
In the image provided, I drew a bar graph on the whiteboard as an example. On this bar graph, it shows the career scoring average of 4 hall of fame basketball players and they are Dennis Rodman, Michael Jordan, Magic Johnson, and Larry Bird.
The bar graph tells us the Rodman's scoring average was approximately 7 points per game. Jordan's scoring average was approximately 30 points per game, Johnson's scoring average was approximately 20 points per game, and Bird's scoring average was approximately 24 points per game.
I have also provided 2 questions.
In part A, we are asked who had the highest average. We can see that Jordan had the highest average simply because Jordan has the highest bar.
In part B, we are asked to find the difference between Bird's average and Rodman's average. We can see that Bird's average was approximately 24 points per game and Rodman's average was approximately 7 points per game.
So the difference between their averages is approximately 24 - 7 or 17 points per game.
