A pictograph depicts the income levels of workers with different degrees using four blocks.

A graph is deceptive in nature when the reader is unable to get a clear or accurate perception of the data. A graph can be inferred as deceptive when compared to the actual data.

The actual incomes along with the academic degrees are:

The graph denotes income levels in the form of 3-D images. Visually, the reader would judge the results by the volume of the cubes.

By observing the graph, the difference in the income levels appears to be huge as the volume of successive blocks increases by a large amount when the actual increase in the income level is small.

For example, the difference in the volumes of the blocks corresponding to the income level of 鈥淎dvanced degree鈥� and 鈥渘o High School Diploma鈥� appears to be approximately 10 times. The real increase in the income level of workers with the two types of qualifications is approximately thrice.

Therefore, the given graph inaccurately represents the increase in income level of workers with the different kinds of degrees and leaves a false impression in the minds of the readers.
