Final answer:
In bar graphs, specific data is represented by bars, each depicting a particular category's numerical or percentage value, and they are separated by gaps. Bars do not have to be ordered from least to greatest and data is not displayed in intervals.
Step-by-step explanation:
Which of the following are true of bar graphs?
- C. Specific data is shown: Each bar represents a specific category with a numerical or percentage value, indicating the number or percent of individuals in that category.
- D. There are gaps between bars: To make the distinction between categories clear, bars are separated from one another.
It is not necessary that bars be in order from least to greatest; they can be arranged in any order that serves the purpose of the data presentation, although a Pareto chart does sort the bars from largest to smallest. Also, data is not displayed in intervals in a bar graph; that characteristic is more typical of a histogram.
