Question

A gardener measures every plant in her garden and notes that 28% are under 6 inches, 54% are between six and 8 inches and the rest are above 8 inches. if she wants to make a bar graph to depict her data, where should the vertical axis begin to ensure it’s not misleading?

Answer 1

The vertical axis will start from 0 inches.

Explanation:

• As data provides information that
• 28% plant are under 6 inches.
• 54% are between six and 8 inches.
• 18% are above 8 inches.
• So the least height is not mentioned only it is mentioned that below the 6 inches which means from 0 inches to six inches.
• And in making bar graph vertical axis should start from least value.
• Hence here possible least value is 0 inches.

Answer 2

The vertical axis should begin with 0 inches.

Explanation:

The vertical axis must start with 0 inches to ensure accuracy for the measures of every plant since 28% of the plants in the garden are under 6 inches.

If the vertical axis begins with 6 inches or above, we can miss a lot of the gardener's data, especially the plants which are under 6 inches.

Therefore, to ensure that the graph does not mislead any measures of the plant, the vertical axis must begin with 0 inches.
