*1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph.**Bar Graph*

**Advantages - Comparing data across categories.**

**Disadvantages - Can't compare two or more different sets of data and depending on the scale or interval, the exact number is not clear or can be difficult to identify.**

*Ex.*

*Double Bar Graph*

*Advantages - Comparing 2 sets of data across categories.*

*Disadvantages - *If a double bar graph has too many series of data it could be confusing to read. Also depending on the scale or interval, the exact number is not clear.

*Ex.*

*Line Graph*

*Advantages - Shows changes in data over time.*

*Disadvantages - *Just like a bar graph,and double bar graph depending on the scale or interval the exact number is not clear.

*Ex.*

*Circle Graph*

*Advantages - Comparing categories to whole in percentage.*

*Disadvantage - You have to calculate the percentage of each piece of data.*

*Ex.*

*Pictograph*

*Advantages - Comparing data that can easily be counted, and represented using symbols.*

*Disadvantages - *Hard to find the exact amount of partial symbols.

*Ex.*

*2. How can graphs be misleading. Show 3 ways.*

* * Distorting the scale (break in the y-axis)*

**Distorting the visual (making a symbol appear larger than others *Pictographs only)*
