Is a histogram the same as a bar graph?

• Yes, because they both use intervals.
• No, because a histogram displays numerical data while a bar graph displays categorical data.
• Yes, because they both use bars to display data.
• No, because a histogram displays categorical data while a bar graph displays numerical data.
