7361604345 | Shape (of a histogram) | A description of a histograms Modes, Symmetry, Outliers, and Gaps. | 2 | |
7361610542 | Center (of a histogram) | The place in the distribution of a variable that you'd point to if you wanted to attempt the impossible by summarizing the entire distribution with one number. Measurements include Mean and Median. | 3 | |
7361620976 | Spread (of a histogram) | A numerical summary of how tightly the values are clustered around the center. Measures include IQR (Interquartile Range) and Standard Deviation. | 4 | |
