Question

Which of the following represent common mistakes found in graphs published in everyday media outlets?

1) Using a compressed scale on the Y-axis (e.g. not including the zero point).
2) Using a pictogram in which the images do not vary in width as well as height.
3) Using a 2-D rather than a 3-D graph to highlight differences.

Answer 1

Three common mistakes found in graphs published in everyday media outlets are using a compressed scale on the Y-axis, using a pictogram with images that do not vary in width as well as height, and using a 2-D instead of a 3-D graph to highlight differences.

Step-by-step explanation:

Three common mistakes found in graphs published in everyday media outlets are:

1. Using a compressed scale on the Y-axis (e.g. not including the zero point). This can exaggerate differences and make trends appear more dramatic than they actually are.
2. Using a pictogram in which the images do not vary in width as well as height. This can distort the data and misrepresent the quantities being compared.
3. Using a 2-D rather than a 3-D graph to highlight differences. 2-D graphs are simpler and easier to interpret, while 3-D graphs can create misleading visual effects.
