| Q3 | $1,500,000 | $3,750,000 |
| This fall | $1,750,000 | $4,375,000 |
The corrected axes on the left present a gradual enhance in gross sales. Nevertheless, the wrong axes on the proper make it seem that gross sales have elevated by a lot bigger quantities, because of the suppressed y-axis scale.
By omitting or misrepresenting the axes, statisticians can distort the visible illustration of knowledge to magnify or reduce developments. This will mislead audiences into drawing inaccurate conclusions.

Drawing conclusions from a small pattern measurement could be deceptive, as it might not precisely symbolize the bigger inhabitants. For instance, Gates may cite a survey of 100 folks to assist a declare about the whole nation.
Examples of Innuendo and Implication
| Instance | Implication |
