A picture graph is a visual method of displaying information that uses images or symbols to represent data. It includes a key or scale that indicates the value of each picture.
Know MoreOne benefit of a picture graph is that it makes it easier for people to understand information. Data presented verbally is usually clarified when a picture graph is utilized.
Picture graphs, however, often do not display data as accurately as other types of graphs. For example, in a picture graph illustrating the number of cars a dealership sells each month, an image of one car represents 10 cars sold. If the dealership sells 12 cars, the picture graph shows an image of one car along with a small portion of another car. This makes it difficult for the person viewing the graph to know exactly how many cars the dealership sold.

Full Answer >An ogive graph is a smooth S-shaped curve that is used in statistics. The graph is obtained by plotting the values of cumulative frequency against the upper boundary points of the class intervals.
Full Answer >A nonlinear graph is a graph that depicts any function that is not a straight line; this type of function is known as a nonlinear function. Linear functions, or those that are a straight line, display relationships that are directly proportional between an input and an output while nonlinear functions display a relationship that is not proportional.
Full Answer >To graph a math equation, acquire some graphing paper, draw x and y axes, and decide whether the equation is linear or non-linear. Approach the problem by finding the slope of the linear equation or using a table for a non-linear one.
