Histograms, Bar Graphs, & Circle Graphs

Histograms:

    -A lot like bar graphs but the main difference is that they MUST have order.
*Give the graph a title and label the x & y axis
    -Pictures of Histograms:

 
 

Bar Graphs:

*Order does not matter!!!

Circle Graphs:

  -These represent categorical data and also part of a whole.
 
  1. The first step is to lay out all of the information on a dot plot
  2. Find the decimal of each number out of the whole.
  3. convert the decimals into percents.
  4. Multiply the decimals by 360 to find out how big to make the portion of the graph.
  5. Make sure to have protactor and a ruler!!

    I know that the difference between histograms and bar graphs is something that was important to understand, especially for students. I think you did a great job showing the difference between the two.
