Résumé
We present the results of an investigation into the mistakes and difficulties of students to teachers of Primary Education in the location of points and in the assessment of increases in temporary graphics. The results show that the students to teachers make few errors in the location of points on the chart, but in most cases, they have no method to compare and evaluate changes in a graphic timeline. Our proposal is that, in the training of mathematics teachers, the knowledge of ratio, proportion, percentages and percent variations (increase and decrease) in statistical contexts should be promoted.
