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.
Know MoreBar 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.
Learn more about Data GraphsA stem and leaf plot with decimals is an organized representation of the frequency with which certain numbers containing decimals occur in a set of data. Stem and leaf plots can be applied in a number of different fields for bookkeeping and to help keep sets of information analyzed. There are also forms of stem and leaf plots that are charted the same way, but do not use decimals.
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 >To make a stem and leaf plot, organize the data in a list with the same first numbers together. Then write the stem numbers on one side of the chart and the leaf numbers out to the side by the appropriate stem numbers.
Full Answer >A bar graph is used to compare items between different groups and track changes over a period of time. Bar graphs are best used for changes that happen over a large amount of time instead of just months or weeks.
