  "definition": "1. A graphic representation of the frequency distribution of a continuous variable. Rectangles are drawn in such a way that their bases lie on a linear scale representing different intervals, and their heights are proportional to the frequencies of the values within each of the intervals.\n\n2. The purpose of a histogram is to graphically summarize the distribution of a univariate data set. The histogram graphically shows the following: (a) center (i.e., the location) of the data; (b) spread (i.e., the scale) of the data; (c) skewness of the data; (d) presence of outliers; and (e) presence of multiple modes in the data. These features provide strong indications of the proper distributional model for the data. The probability plot or a goodness-of-fit test can be used to verify the distributional model.\n\n3. A graphical display of a statistical distribution; a form of bar chart. One axis (usually x) is the scale of the values observed, the second (usually y) is the frequency that observations occur with (approximately) that value.",
