Four graphs A, B, C and D. Each graph is a line that occupies a square. The left and right sides of the graph touch the x axis. Each graph has a different shape, but the space under the line remains the same. Graph A. Solid line symmetrical bell-shaped curve. Graph B. Dotted line symmetrical bell-shaped curve superimposed on a solid asymmetrical curve that leans to the right of the dotted curve. Graph C. Dotted line symmetrical bell-shaped curve superimposed on a solid curve. The solid curve is symmetrical. It goes up on both ends to form two humps and it is lower in the middle. The solid curve looks like the letter M. Graph D. Dotted line symmetrical bell-shaped curve superimposed on a symmetrical curve that is narrower and taller than the dotted line curve.
