Example 3

medium
A pictograph shows the number of goals scored by four teams. Each football symbol = 3 goals. Team W: 6 symbols, Team X: 4 symbols, Team Y: 7 symbols, Team Z: 5.5 symbols (half symbol included). How many more goals did Team Y score than Team Z?

Solution

  1. 1
    Step 1: Team Y: 7×3=217 \times 3 = 21 goals. Team Z: 5.5×3=16.55.5 \times 3 = 16.5 goals.
  2. 2
    Step 2: Difference: 21−16.5=4.521 - 16.5 = 4.5 goals. Since goals are whole numbers, Team Z likely scored either 16 or 17 goals, giving a difference of 4 or 5 goals.

Answer

Team Y scored approximately 4 to 5 more goals than Team Z (21 vs 16.5).
When comparing values from a pictograph, multiply each count of symbols by the key value and then subtract. Half symbols introduce slight imprecision, which is a limitation of pictographs for representing exact values.

About Pictograph

A pictograph (or picture graph) displays data using pictures or symbols, where each picture represents a specific quantity. For example, if 🍎 = 5 apples, then 🍎🍎🍎 means 15 apples. A key (legend) always tells you what each symbol represents.
