In what way is the bar graph better than pictograph?
Answer Expert Verified Bar graph is better than a pictograph when the exact quantities of the commodities represented are to be known. In a pictograph, one needs to count all the symbols/icons and then multiply with the scale factor. Bar graphs are better indicative as they show exact numerical value.
