Blog #4

Hello Class, today we will be learning about different types of graphs. Graphs are visual aids used to represent a set of data in a word problem.


  • One type of graph is a bar graph. These graphs can be shown horizontally or vertically. These graphs are usually helpful for comparing two or more sets of data.

  • Another graph is called a circle graph, or a pie chart. The data is divided into "slices" of the pie and paired with a color.

  • Another type of graph is a line graph. This is when the data in the word problem is plotted on a graph with an (X,Y) coordinates.



  • The last type of graph is a histogram which is almost like a bar graph but a little different.  Unlike a bar graph a histogram the bars must be touching, and the data must be put in order on the graph.
