What is a Histogram Useful for?
Answer
A histogram is an important device for exploring the shape of the distribution of the values of a variable. Histograms are used for checking normality, screening of outliers, or suggesting another parametric shape for the distribution. A histogram basically breaks the range of values of a particular variable into intervals of equal length.
