-You can use bar graphs, circle graphs(uses percents), and a number line.

-There is a y-axis and x-axis with 4 quadrants. The first quadrant is ++. The second is +-. The third quadrant is -- and the fourth quadrant is -+. The quadrants are labeled as roman numerals. Finally, the origin is in the middle of the graph. The coordinates of the origin is (0,0).

-There are double line graphs and double circle graphs.

What I know that would improve my test scores.

I would study more so that I can remember the answers easily.

QUESTION 8

a) Explain how this graph could be misleading. This graph is misleading because Scott's bar is more wide than Bryce's and there is a break in the X-axis.

b) What conclusion does the graph suggest about Scott's progress compared with Bryce's progress? Scott's progress looks far more ahead of Bryce's but, its only 1 more interval then Bryce.

c) Describe how to redraw the graph to represent the data more accurately. I would make the bars equal in size, I would take away the break in the X-axis and shorten the graph to make it less misleading.

Note: I forgot how to get pictures from mytextbook.ca.
