Description: Statistical information is provided in two ways in this task: on the one hand, by means of a table and on the other hand, by means of a histogram. The aim is for the students to read the information comprehensively and for them to be able to infer consequences once the information has been read. The histogram is a population pyramid but not placed in the usual way which makes it rather more difficult to read and interpret the data.
One of the questions involves performing a calculation to discover the percentage of an age group in relation to the whole population. It is a little more complicated task.
They are also asked to search for data in one that they consider relevant and discuss it, where the aim is to foster the initiative and autonomy of the students.
In the second part of this task, the students are asked to compare the data of a table with the sector diagrams that they represent. They may have to perform a calculation, but they should be asked to avoid it as far as possible.
Competences:
Reading, carefully, and interpreting, critically, the statistical information contained in tables, graphs, diagrams or texts, and distinguishing between relative and absolute data (percentages, rates).
Solving, in a reasoned and critical manners, problems that require the use and interpretation of absolute and relative statistical data and/or statistical parameters.
