Which of the following questions about comparing and ranking categories is best answered by a bar chart? Will the user be looking for a concentration of occurrences at particular values? Does the user need to understand how values are distributed? Does the user need to determine whether a change to one variable has an effect on another variable and what that effect is? Does the user need an approximation of the values and not a precise numeric value?
