Advertising exaggerates the gap by reducing the proportion

Yet, as it turns out, there are plenty of ways graphs can mislead and outright manipulate.Here are some things to look out for.In this 1992 ad, Chevy claimed to make the most reliable trucks in America using this graph.Not only does it show that 98% of all Chevy trucks sold in the last ten years are still on the road,but it looks like they're twice as dependable as Toyota trucks.That is, until you take a closer look at the numbers on the left and see that the figure for Toyota is about 96.5%.The scale only goes between 95 and 100%.If it went from 0 to 100,it would look like this.
