A histogram is a polygon composed of a sequence of rectangles aligned at a common base line. The rectangles have equal widths but may have different heights. For example, the figure on the left shows the histogram that consists of rectangles with the heights 2, 1, 4, 5, 1, 3, 3, mea...

Histograms are useful for showing the distribution of a single scale variable. Data are binned and summarized by using a count or percentage statistic. A variation of a histogram is a frequency polygon, which is like a typical histogram except that the area graphic element is used instead of ...

The data in a frequency distribution can be presented using a histogram. A histogram is a bar chart with different intervals on the X-axis and the absolute frequencies on the Y-axis. The histogram for our data is presented below: Frequency Polygon A frequency polygon is similar to a histogra...
A frequency distribution is a collection of data that specifically identifies how often each entry in a sample space occurs within a given data set. Frequency distributions can be generated either for each individual data point in...
Histograms and frequency polygons are two graphical representations of frequency distributions: (a) A histogram or frequency histogram consists of a set of rectangles having: (1) bases on a horizontal axis (the x-axis) with centers at the class midpoint and lengths equal to the class interval...
