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 ...
Histograms provide a great way to evaluate data. They can be used to check data for extreme values, or outliers, and to help understand the distribution of your data. The distribution of a variable is important to understand when selecting appropriate statistical analysis tools.See...

Density Plots show the distribution of a variable in the form of a smooth curve, akin to making a topographic map of data. They are similar to histograms but display the distribution in a more fluid manner without the distraction of 'binning bias' — the potential distortion of data distribut...

A histogram is an accurate graphical representation of the distribution of a numeric variable. It takes as input numeric variables only. The variable is cut into several bins, and the number of observation per bin is represented by the height of the bar. ...
a bar graph of a frequency distribution in which the frequency of a variable is represented by the height of the bar, and the class interval by the width, where each class interval is a summary of data that represents a range of independent variable values rather than a single value. ...
Histograms are important tools for displaying the frequency distributions, showing how repetitive a value is in each set. Given below are some common histogram shapes that represent the different distribution of the data. 1. Normal Distribution ...

A histogram represents the frequency distribution of a quantitative variable, whose values represented on the X-axis are sorted in ascending order. Therefore, the first step to elaborate a histogram is building the frequency distribution table. As presented in Sections 3.2.2 and 3.2.3, for each ...
