Welcome to MooMooMath where we upload a new
Math video everyday In this video I would like to talk about the
difference between a histogram and a bar graph. A histogram and a bar chart both ways to graph
data. Both have an x and y axis, and both use a
bar to display the data. With a histogram the categories are numerical.
For example, notice on this histogram the x axis is the age of people in the room. The
ages are grouped in a numerical range. In this next example, the histogram is graphing
the score on a test and the number of people who scored in each range.
Also, the bars of a histogram touch A bar graph uses categories such as types
of movies, color of eyes, and the bars do not touch
For example, in this bar graph the categories are grade level and the number of students
in each grade level. Notice that the bars do not touch
In another example, the categories are types of videos and the number of videos in each
type. Again, the bars do not touch
In summary, histograms have bars that touch and use quantities.
A bar graph have bars that don’t touch and use categorical data.
