what is a key difference between a histogram
and a vertical bar graph?
histograms represent
categorical data, while
bar graphs represent
numerical data.
histograms have no gaps
between bars, unlike
vertical bar graphs.
bar graphs show
frequency, while
histograms show
percentages.
histograms use
horizontal bars, while bar
graphs use vertical bars.

Explanation:

• Option 1 is incorrect: Histograms represent numerical (continuous) data, while bar graphs represent categorical data, which is the opposite of the statement.
• Option 3 is incorrect: Both histograms and bar graphs can show frequency or percentages; this is not a defining difference.
• Option 4 is incorrect: Both can use vertical or horizontal bars; the orientation is not a key difference.
• Option 2 is correct: Histograms have adjacent bars with no gaps because they represent continuous numerical data ranges, while vertical bar graphs have gaps between bars to separate distinct categorical groups.

Answer:

1. Histograms have no gaps between bars, unlike vertical bar graphs.
