Introducing graphs!

When teaching students about graphs it can be introduced as Statistics!
To start you can show the students different graphs and talk about what the data represents. Choose topics they will be interested in.

Now it is time to introduce the types of graphs! 
First have the students gather the information for their "Data Analysis"
Then have them decide which graph works best!!
Bar Graph! A bar graph is best for comparing data in categories. Order is not required here. Spaces between the bars are required .
EXAMPLE:


Histogram graph! Best for comparing data ranges in order.  NO SPACES between the bars and the intervals much be the same.





Line Graph! Show information over time.  The data is continuous. Shows trends!

Circle Graph/Pie Chart! Represents parts of a whole to compare the parts that make up 100%


Scatter Plots! Show relationship between two sets of data!


Stem and Leaf! Shows the values of each interval!


Double Bar graph!! Comparing data in categories showing two sets of data!
Pictograph! Using pictures to represent the data. Often the pictures represent a value.
Dot Plot! Shows information in clusters! 

It is really important that your students always have a TITLE and make sure they read ALL LABLES when answering questions about graphs (This will help with standardized tests). The descriptions of each graph should help the students know which graph to use!!!

Once the student has all their data, they will select a graph and add their data!! In our class we did pie charts of our day here is mine!!!
