Interpret graphics e table can be considered a challenge For those who are preparing for the vestibular. It is common for tests to cover such questions, which demands more attention from those who are answering the questions.
HAS CNNthe math teacher Daniel Ferretto listed 4 Tips that can help students.
See below:
Always start with the statement and read well
Before looking at the chart, it is necessary Read the statement carefully. This is because it indicates exactly what should be observed and avoids unnecessary analysis. It is also recommended that students notice titles, subtitles e units.
“These elements explain visual content. Ignoring them can lead to interpretation errors, especially in logarithmic scales or nonlinear proportions,” explains Ferretto.
Identify the axes and their variables
In line or bar graphs, the x axis usually represents the time or categories, and the Y axis shows the values. Remembering this information streamlines reading. Students should also observe trends, not just numbers.
“More than“ how much is worth ”, entrance exams often ask how it varies. Growth? Fall? Picos or stability?” Says Ferretto.
Attention with pranks and remember the context
Trunched scales (which do not start from scratch) or disproportionate representations can generate confusion.
Another important point concerns the data. Ferretto points out that students must relate information to the context. “No, graphics often appear on interdisciplinary issues. Ask yourself: what does this data say about society, the environment or economy, for example?”
Typical Enem Issues
Ferretto recalls that in one of Enem’s previous editions, a matter of humanities had a bar chart compared the average income of men and women in different sectors of the economy.
The question, in turn, required not only data reading, but also critical interpretation of gender inequality. “This is a great example of how visual reading is interconnected to the content of various areas of knowledge,” says the professor.
In and nature sciences, it is common to use graphs to represent physical phenomena, statistics and probabilities. Knowing how to identify the type of chart (columns, lines, sectors) and the main message can be decisive to get the issue right. It is a strategy for gaining speed and confidence in visual reading.
