Several types of graphs are used for displaying information in mathematics including the bar graph; pie chart or circle graph; histogram; stem and leaf plot; dot plot; scatter plot; and time-series graphs. The type of graph chosen depends on whether the data is quantitative, qualitative or paired.
Continue ReadingBar graphs are used for displaying qualitative data. Each category in a set of qualitative data is represented by a bar, and the bars are arranged by order of frequency. Pie or circle graphs display data in the form of a pie. Each "slice" of the pie represents a different data group. A histogram is similar to a bar graph in that it uses bars, but it displays quantitative versus qualitative data.
Stem and leaf plots divide quantitative data by the highest data point and the remaining points of value. The stem is used for the highest data point, while the leaf is used for the other values. Dot plots are graphs that combine the concepts of histograms and stem and leaf plots. Scatter plots display paired data using horizontal and vertical axes. Trends in the data are illustrated through correlation and regression. Time-series graphs display data at different points in time, showing trends in data.

For example, a bar graph representing state employment rates can be turned into a compound bar graph by subdividing each state bar into columns to show unemployment percentages based on gender or race.
Full Answer >Printable graph paper is available in a variety of sizes and formats, including standard 1/4-inch graphs, numbered grid paper with 10 lines per inch and trigonometric graphs labeled in radians. Exact availability depends upon the website. For example, PrintFreeGraphPaper.com offers a simple-to-use selection tool to download isometric, hexagonal and engineering graph papers in PDF formats, as well as standard Cartesian graph paper and logarithmic, polar and Smith chart paper.
Full Answer >The term interactive graph paper refers to digital graphs available on the Internet or in software that allow the user to draw graphs by hand or input functions with which a program draws the graph. Interactive graph paper is a useful tool in education for classroom lectures.
Full Answer >To graph a function, create a table containing several ordered pairs, and plot the points on a graph. Depending on the type of function, the number of ordered pairs needed can vary. Use your own discretion when determining how many points are enough.
