Step-by-step explanation:
An important consideration when using pictographs to represent data is that the proportions of the pictographs must be accurate. This means that each pictograph should accurately represent the quantity or value it is intended to portray. For example, if one pictograph represents 5 students and another represents 10 students, the second pictograph should be twice as large as the first. This ensures that the pictograph is visually accurate and can be interpreted correctly.
