Step-by-Step Solution
A bar graph displays discrete categories with gaps between bars, whereas a histogram displays continuous grouped data with bars touching.
Answer: A) Bar graph
A histogram is used to display continuous (grouped) data and its bars touch each other with no gaps. Which chart, by contrast, is used for separate, discrete categories with gaps between bars?

Key idea: Histograms — bars that touch
A histogram is a bar graph for **grouped** data:
- The -axis shows class intervals (continuous, so bars TOUCH).
- The -axis shows frequency.
- Bar widths are equal (one per class).
- Bar height = frequency of that class.
Difference from a regular bar graph: bar graphs separate distinct categories with gaps; histograms show continuous data with no gaps.
- The -axis shows class intervals (continuous, so bars TOUCH).
- The -axis shows frequency.
