Histogram [ˈhɪs.tə.ɡræm]: A visual representation of a distribution of data that is divided into intervals. For each interval the amount of values that belong to it are counted and then represented by the interval’s column’s area.
In most cases, the intervals will be of
equal size, so the columns’ height will be proportional to the frequency of values in each interval. It is also possible to use differently sized intervals. However, since the area is scaled – not the height, like in bar charts – these histograms are not as easy to read and therefore used less often.[button url=”http://journocode.com/data-journalism-dictionary/” new_tab=”” button_style=”btn-info” button_size=”btn-default”] Back to Dictionary[/button]
