One of the key differences between a bar chart and histogram is: the histogram contains gaps between the bars and the bar chart does not. a bar chart is used to display a categorical variable and a histogram is used to display the distribution of a quantitative variable. the histogram shows relative frequency while the bar chart shows frequency. the bar chart must be vertical while the histogram must be horizontal.

Select ALL the graphs listed below that should only be used for categorical (also known as qualitative) data. scatter plot time-series graph multiple bar graph bar graph ogive pie chart relative frequency polygon stemplot frequency polygon pareto chart relative frequency histogram histogram
A bar chart and a Pareto chart both use bars to show frequencies of categories of categorical data. What characteristic distinguishes a Pareto chart from a bar chart, and how does that characteristic help us in understanding the data?
