A graph for nominal or ordinal data with separated bars is a

• A. Bar Graph
• B. Histogram
• C. Line Graph
• D. Pie Chart

Answer: (A)

Bar graphs are used to display categorical data, where each category is distinct. For nominal data (like fruit types) or ordinal data (like rating levels), you draw a separate bar for each category. The gaps between the bars emphasize that the categories are separate, not parts of a continuous scale, and the height of each bar shows the frequency or proportion for that category. This is different from a histogram, which is for numeric data that can take many values on a continuous scale and has touching bars to reflect that continuity. A line graph connects data points to show trends over an ordered variable, and a pie chart slices a circle to show parts of a whole. So, for nominal or ordinal data with separated categories, a bar graph is the right choice.
