This elementary school math tutorial from NutshellMath offers introductory homework help in choosing an appropriate graph to represent data. Graphs are important tools in mathematics for visualizing groups of numbers and other information. Since not all groups of data are the same, it is best to use different graphs to represent different groups of data. This tutorial introduces many different types of graphs, and presents the features of each which make them suitable for different types of data.
Two types of graphs are introduced that are best for comparisons of people or categories that have numbers associated with them. An example of such data would be the number of marbles of various colors in a box. There would be a number of marbles associated with each color of marble. For data such as these, a bar graph or pictograph can be used. Bar graphs will represent data as bars of varying length, while pictographs will use small rows of images to represent multiples of the data. Another type of graph, a stem-and-leaf plot is best used to represent groups of numbers by themselves. An example of such data would be a set of times from a repeated trial. The stem and leaf plot collects numbers together and can reduce long lists to be viewed more easily. Using a stem-and-leaf plot, it is easier to find the median, or middle number from the data, as well as the range. The last type of graph, a circle graph, represents data as segments of a circle. This graph is best used to represent percent, or pieces out of a whole.
The homework help offered in this tutorial will explain how to use graphs to represents data, and how to select an appropriate graph for a given group of data. This explanation will help in solving homework problems involving graphs and using graphs to represent data.
