Question

1 what do bars on a histogram indicate?
the range in the difference of the categories
how many different categories are described
the average data in each category
frequency or relative frequency of the data in the category

Explanation:

To determine what the bars on a histogram indicate, we analyze each option:

• "The range in the difference of the categories" is incorrect. Histogram bars don't represent the range of category differences.
• "How many different categories are described" is incorrect. The number of categories is shown by the number of bars, not what the bars themselves indicate.
• "The average data in each category" is incorrect. Histograms show frequency, not average.
• "Frequency or relative frequency of the data in the category" is correct. In a histogram, each bar's height (or length, depending on orientation) represents the frequency (or relative frequency) of data within a particular interval or category.

Answer:

D. Frequency or relative frequency of the data in the category (assuming the options are labeled A - D in order as presented, with the last option being D)
