Direct square proportion is the relationship between two things in which the quantity of one is directly proportional to the square of the other. In this relationship, the ratio of the first to the square of the second is a constant.
Know MoreAn example of direct square proportion is when a circle is directly proportional to the square of its radius. This example is expressed by an equation stating that the area of a circle is equal to the constant multiplied by the square of the radius. Direct proportion is the relationship between two things in which the quantity of one is directly proportional to the other, without the second quantity being squared. In this type of proportion, the two quantities change by the same factor.

According to the American Society of Quality, a scattergram illustrates pairs of numerical data on graphs with one variable on each axis to explore the relationship between them.
Full Answer >A line graph is a graph that charts the relationship between two variables or a progression of a single quantity through time. Without the lines connecting points of data, it would be difficult to make sense of the data being presented if there was no overall trend between the dots. A bar graph, on the other hand, is meant to compare two or more statistics, such as population figures.
Full Answer >A scatter plot is a mathematical diagram showing the relationship between two sets of data. Individual points are positioned according to the variables assigned to the vertical and horizontal axis.
Full Answer >A metaphor is a direct comparison between two things that are not like one another but are considered essentially linked in some way. A familiar thing is compared to something unfamiliar to improve the understanding of a reader or listener. Metaphors are often used in highly descriptive or romantic writing.
