□ data are organized by categories.
□ data are organized in equal intervals.
□ bars can go in any order.
□ bars must appear in numerical order.
□ bars are not touching.
□ bars are always touching.

Explanation:

• In a histogram, data is organized into equal - width intervals (not categories like in a bar graph for categorical data). So, "Data are organized in equal intervals" is correct.
• The bars in a histogram must appear in numerical order of the intervals. So, "Bars must appear in numerical order" is correct.
• Also, in a histogram, the bars are always touching (since the data is continuous within the intervals). So, "Bars are always touching" is correct.

Answer:

Data are organized in equal intervals, Bars must appear in numerical order, Bars are always touching.
