2. Stem-and-leaf display - Wikipedia

   en.wikipedia.org/wiki/Stem-and-leaf_display

   A stem-and-leaf plot of prime numbers under 100 shows that the most frequent tens digits are 0 and 1 while the least is 9. A stem-and-leaf display or stem-and-leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution.

3. Plot (graphics) - Wikipedia

   en.wikipedia.org/wiki/Plot_(graphics)

   Stemplot : A stemplot (or stem-and-leaf plot), in statistics, is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution. They evolved from Arthur Bowley's work in the early 1900s, and are useful tools in exploratory data analysis.

4. Mode (statistics) - Wikipedia

   en.wikipedia.org/wiki/Mode_(statistics)

   The mode of a sample is the element that occurs most often in the collection. For example, the mode of the sample [1, 3, 6, 6, 6, 6, 7, 7, 12, 12, 17] is 6. Given the list of data [1, 1, 2, 4, 4] its mode is not unique. A dataset, in such a case, is said to be bimodal, while a set with more than two modes may be described as multimodal.

5. Mathematical statistics - Wikipedia

   en.wikipedia.org/wiki/Mathematical_statistics

   Statistical theorists study and improve statistical procedures with mathematics, and statistical research often raises mathematical questions. Mathematicians and statisticians like Gauss, Laplace, and C. S. Peirce used decision theory with probability distributions and loss functions (or utility functions).

7. Shape of a probability distribution - Wikipedia

   en.wikipedia.org/wiki/Shape_of_a_probability...

   The shape of a distribution will fall somewhere in a continuum where a flat distribution might be considered central and where types of departure from this include: mounded (or unimodal), U-shaped, J-shaped, reverse-J shaped and multi-modal. [1]
