Different Types of Graphs

1
Bar Graph
Advantage - Bar graphs are good at comparing data across categories
Disadvantage - Depending on the scale, he exact number could be difficult to identify

Line Graph

Advantage - They are good at showing data over time

Disadvantage - You can only compare rates of your own trends rather than multiple trends

Circle Graph

Advantage - You can compare portions out of a whole

Disadvantage - You have to find the percent of the portion and divide it into the whole

Pictograph

Advantage - It uses symbols to represent data

Disadvantage - The symbols make it hard to determine the data

Double-bar Graph

Advantage - It can compare two sets of data across categories

Disadvantage - it takes to long to construct

Misleading Graphs

One way you can make a graph misleading is by making one of the graphs wider than the other. Another way to make a graph misleading is making a bar a different color than the other ones. You can also make a graph misleading by making one of the bars 3D.

2 a)

Two graphs that would show this data accurately are line graphs or bar graphs. A line graph would be good because it is good at showing data over time. A bar graph would work because it is good at showing data across categories.

2 b)

If i were selling pizza subs i would keep going because it seems like you are selling more pizza subs every week so if I keep going i would be selling more pizza subs.

4

I would choose the pictograph because it grabs your attention more.

4 a)

I would make each heart a total of 2 instead of 4 to show it increases even more.
