Read the picture-graph key before counting symbols
Explain what each symbol represents before comparing category totals.
Four pictures need not represent four responses. Begin with the key and translate a small section together, including any partial symbol whose meaning the graph explicitly defines.
If one picture represents one response, four pictures indicate four responses in that category.
What does one picture stand for?
Set the symbol key. Place symbols according to counts. Read a category using that key.
Read the key before counting picture symbols. A partial symbol needs an explicit meaning when it represents less than the full key amount.
What quantity does one symbol stand for? Begin with one-to-one symbols only.
Changing a key changes how symbols must be interpreted.
