How can the choice of graph type affect the interpretation of data?

Back

Different graph types (e.g., bar graphs, pie charts, line graphs) can emphasize different aspects of the data, potentially leading to different interpretations depending on how the information is presented.

What does it mean for a graph to have an 'even scale'?

Back

An even scale means that the intervals on the axes are consistent and proportional, allowing for accurate comparisons between data points.

Front

What are some techniques used to mislead viewers with graphs?

Back

Techniques include manipulating the scale, omitting data points, using inappropriate graph types, and altering the visual representation (e.g., 3D effects) to exaggerate differences.

What is the significance of labeling axes in a graph?

Back

Labeling axes is crucial as it provides context for the data being presented, helping viewers understand what is being measured and the units of measurement.
