Melody's Graph Post

1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph.
Bar graph advantage- Compare data across categories.
Disadvantage- Sometimes it's inaccurate.

Double bar graph advantage- Compare two sets of data across categories.
Disadvantage- Can only compare two sets of data.

Circle graph advantage- Best for comparing categories to the whole using percents.
Disadvantage- It is hard to compare two sets of data

Pictograph advantage-Easy to read and can show data clear.

Disadvantage-Have to calculate to know data.

Line graph advantage- Shows the change in the data over time.

Disadvantage- Can only show one set of data.

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

a) Distorting the size of the visual.

b)Making a break in the y-axis.

c)Distorting the size of the bars

Heres a video to help you with bar graphs.
