During a practical History class, 6th-grade students were challenged to investigate how many students were born in each decade starting from 2010, in order to understand the age distribution in the class. After collecting the data, the teacher suggested representing this information in a bar graph, pointing out that this visualization could help in comparing the number of births in different decades. Additionally, the teacher proposed a reflection on how historical events can influence the birth rate in certain decades. Considering the interdisciplinary context presented and the need to present the data clearly and efficiently, how could the students organize the collected data and express it graphically?

Students can organize the collected data on the number of births in each decade starting from 2010 and express them graphically in a bar graph, where each bar represents a decade and the height of the bar is proportional to the number of students born in that decade.

Students can organize the data in a simple list, placing the number of births in each year, without the need for a graph for comparison.

Students can use a scatter plot to show the relationship between students' age and decade of birth, with each point representing a student.

Students can represent the collected data in a pie chart, where each sector represents a decade and the size of the sector is proportional to the number of students born.

Students can create a line graph, where each line would connect the number of births in each year, showing the temporal evolution without the need for bars.
