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 More
Bar 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 Graphs
Graphs provide a means of displaying statistical information in a meaningful way. They allow for concise viewing of statistical data, especially when that data involves data sets numbering in the hundreds or more.Full Answer >
Graphs are beneficial because they summarize and display information in a manner that is easy for most people to comprehend. Graphs are used in many academic disciplines, including math, hard sciences and social sciences. They make appearances in corporate settings, serving as useful tools to convey financial information and facilitate data analysis.Full Answer >
A 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 >
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 >
