Question

the bar chart below shows the speed (in gigaflops using a test package) of several processors. it is intended to be used to compare the overall speeds of the processors for consumers. identify any misrepresentation issues in the graph. select all that apply.

select all that apply:
a: there are no values on the horizontal axis.

b: the horizontal axis ticks are not placed correctly.

c: the vertical axis scale should have a zero break.

d: the vertical axis ticks are not placed correctly.

e: the axis labeling is not complete.

Explanation:

• Option A: The horizontal axis (for processors) has no specific values/names of processors, so this is a misrepresentation.
• Option E: The horizontal axis is labeled "Processor" but has no tick values (like names of processors), and the vertical axis is labeled "Speed" but the horizontal axis lacks proper labeling of what each bar represents (processor names/identifiers), so axis labeling is incomplete.
• Option C: The vertical axis starts at 0, but the bars are close in height. However, a zero break is not needed here as the axis starts at 0. Wait, no—actually, if the goal is to compare speeds, the vertical axis scale here: the bars are from ~150 - 200, but the axis starts at 0. But the main issue with misrepresentation for comparison: if the axis had a zero break (starting above 0), it would exaggerate differences, but here the problem is that the horizontal axis has no values (A) and labeling is incomplete (E). Also, let's re - evaluate:
• A: Horizontal axis (x - axis) has no values (like which processor each bar is for), so we can't tell which bar corresponds to which processor. This is a misrepresentation as the graph is to compare processor speeds.
• E: Axis labeling: The x - axis is "Processor" but has no tick labels (e.g., Processor 1, Processor 2, etc.), so labeling is incomplete.
• Let's check other options:
• B: Horizontal axis ticks placement: There are bars, but no ticks with values, so it's not about placement but lack of values, so B is incorrect.
• D: Vertical axis ticks: The vertical axis has ticks at 0, 50, 100, 150, 200, which are placed correctly (evenly spaced), so D is incorrect.
• C: A zero break is when the axis doesn't start at 0, but here it starts at 0. So C is incorrect.

Answer:

A. There are no values on the horizontal axis.
E. The axis labeling is not complete.
