Question

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

Explanation:

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

• "The range in the difference of the categories" is incorrect. The range of the data set is the difference between maximum and minimum values, not what bars represent.
• "The average data in each category" is incorrect. Histograms do not show averages (like mean, median) of data in categories; they show frequency or relative frequency.
• "How many different categories are described" is incorrect. The number of categories is related to the number of bars, but the bars themselves don't indicate the count of categories.
• "Frequency or relative frequency of the data in the category" is correct. In a histogram, each bar's height (or area, for non - uniform bin widths) represents the frequency (number of data points) or relative frequency (proportion of data points) within that category (bin).

Answer:

Frequency or relative frequency of the data in the category
