Note 1.5

• Our goal is to interpret frequency tables and
  pictographs. Also, we want to be able to create
  frequency tables and pictographs.

5
Frequency Tables

• A frequency table shows how often an item appears
  in a set of data.
• A tally mark is used to record each response.
• The total number of marks for a given response is
  the frequency of that response.

6
Example 1 Use the frequency table of Brads
data.

• How many more chose sports than news?
• Which two programs together have the same
  frequency as adventures?

7
Pictographs

• A pictograph displays data with graphic symbols.
  
• The key identifies the number of data items
  represented by each symbol
• The symbols often represent rounded amounts

8
Example 2 Use the pictograph.

• In which country is the most fish eaten?
• About how many pounds of fish does the average
  person in that country eat in a year?
• How much fish does the average person in the U.S.
  eat in a year?
• The average Norwegian eats about 110 lb of
  fish/yr. How many fish symbols are needed to
  represent this information on the pictograph?

Example 3 Create a pictograph of the medals for
Great Britain.
