Pictograph
Diagram in which the modalities of the distribution of a qualitative statistical attribute or the values of a discrete quantitative statistical attribute are represented by drawings or images.
Therefore, we surveyed 130 students in total.
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.
