# Pictograph

## Pictograph

Diagram in which the modalities of the distribution of a qualitative statistical variable or the values of a discrete quantitative statistical variable are represented by drawings or images.

Pictographs are sometimes called pictograms.

The dimension of a pictograph or the number of pictographs is proportional to the real tally of a modality or a value, or to the frequency of this modality or this value.

### Exemple

In this pictograph, each image corresponds to 5 students surveyed.

Therefore, we surveyed 130 students in total.
