Question

In a joint bar graph the width of all columns should be what​

Answer 1

Step-by-step explanation:

Each bar or column in a bar graph is of equal width and corresponds to the equal class interval. All bars have a common base.

Answer 2

Answer:

Equal

Step-by-step explanation:

• The height of a bar denotes the frequency of data in the interval, while the width of a bar represents a class interval.
• Each column in a joint bar graph has the same width. Height changes because it is a measure of amount.
• A basis is shared by all bars. The data value and the height of the bar are the same. Each bar is separated by the same amount of space.
• We can quantitatively visualize the difference in data thanks to the variation in bar height. However, bars of the same length indicate that the data in the two bars is identical.
• The bar graph is improperly drawn if the spacing and width are not uniform.
