DIAZ-LEVICOY, Danilo; BATANERO, Carmen; ARTEAGA, Pedro    BEGUE, Nuria. Reading a dot plot by Chilean primary education students. []. , 17, 78, pp. 61-67.   02--2021. ISSN 1990-8644.

The aim of this work was to describe the achievement and reading level achieved by 6th and 7th grade of Chilean Primary Education students when working with a dot plot. To achieve this goal, we analyze if they agree with an affirmation based on a dot plot and the justification of the response, by a group of 745 Chilean students. The results show that the majority of students correctly identify the truth of the statement (59.5%), while their arguments fall within a level 0 (47.1%), since they do not address the activity, are unable to make a literal reading of the graph or do not use the data in their justification. In both parts of the task, the 6th grade students have higher achievement than the 7th grade students. The results show this activity presents difficulties for students, so it is necessary to reinforce their work in the classroom.
