Question

what is a bar graph? what is a pareto chart? what is a bar graph? a. a bar graph is a circular graph that uses bars to divide it into segments corresponding to each category. the segments are proportional to the frequency of its category. b. a bar graph represents the frequencies of values either from left-to-right or right-to-left. the different segments of the bar are used to indicate the different frequencies of each category. c. a bar graph is a horizontal or vertical representation of the frequency or relative frequency of the categories. the height of each rectangle represents the categorys frequency or relative frequency. what is a pareto chart? a. a pareto chart is a display of two data sets side by side where the height of each rectangle represents the categorys frequency or relative frequency. b. a pareto chart is a bar graph whose bars are drawn in decreasing order of frequency or relative frequency. c. a pareto chart is a combination of a pie chart and a bar graph.

Explanation:

What is a bar graph?

• Option A describes a pie chart (circular, segments proportional to frequency), not a bar graph.
• Option B's description of "segments of the bar" is incorrect; bar graphs have separate bars, not segments within a bar.
• Option C correctly states that a bar graph is a horizontal/vertical representation of category frequencies, with bar height (or length for horizontal) representing frequency/relative frequency.

• Option A describes a side - by - side bar graph (for two data sets), not a Pareto chart.
• Option B is correct: A Pareto chart is a type of bar graph where bars are ordered from highest to lowest frequency (or relative frequency), which is the defining characteristic of a Pareto chart.
• Option C is incorrect as a Pareto chart is not a combination of a pie chart and a bar graph.

Answer:

C. A bar graph is a horizontal or vertical representation of the frequency or relative frequency of the categories. The height of each rectangle represents the category's frequency or relative frequency.
