WebYou must work out the relative frequency before you can draw a histogram. To do this, first decide upon a standard width for the groups. Some of the heights are grouped into 2s (0-2, 2-4, 6-8) and some into 1s (4-5, 5-6). Most are 2s, so we shall call the standard width 2. To make the areas match, we must double the values for frequency which ... WebHistograms & frequency polygons. Histograms look very similar to bar charts but the bars of a histogram are drawn immediately next to each other. Whereas bar charts represent discrete or categorical data and have gaps between the bars, histograms represent continuous data. There are no gaps between the bars because where one class ends, the ...
WebA note about histograms. When the data represent discrete values such as counts, histograms must be used. When the data represent continuous values, a frequency polygon or histogram may be used. The connecting line of a frequency polygon indicates the continuous nature of the data. WebA histogram is a graphical representation of a grouped frequency distribution with continuous classes. It is an area diagram and can be defined as a set of rectangles with …
