Question

Are Bar Graphs and Histograms the same?

Answer 1

The explanation for the Bar graph and Histogram:

Bar graphs are used to represent categorical data.

In a bar graph, each bar's length represents the number of items in a particular category.

For example, in a bar graph representing the number of citizens living in major cities, “New York” might be one category.

The bars in a bar graph are usually separated from each other.

Also, there is no unique order in which the bars must be drawn, reordering the bars along with their category label does not affect the data represented.

Histograms are used to represent grouped continuous numerical data.

In a histogram, each rectangle's length represents the number of items in a particular numerical interval.

For example, a histogram representing the marks obtained by students in a test might have $10-15$ as one interval.

Also, unlike bar graphs, the rectangles in a histogram graph are stuck together sideways to represent the continuous intervals and they must be ordered according to the numerical interval they represent.

Hence, Bar Graphs are not the same as Histograms.
