Advantages of a pictograph
• A pictograph is easy to read.• 2. They show trends in data
clearly.• 3. They are fun to use.

Disadvantages of a pictographs
• It may be difficult to find a symbol or picture to represent the data.
• 2. The key can be confusing to read. 3. A pictograph can be difficult to make.

Use the data to make a line graph.
• Sam's Weight• Month Weight in Kg• January 49• February 54• March 61• April 69• May 73
