3. List of unsolved problems in statistics - Wikipedia

   en.wikipedia.org/wiki/List_of_unsolved_problems...

   The notable unsolved problems in statistics are generally of a different flavor; according to John Tukey, [1] "difficulties in identifying problems have delayed statistics far more than difficulties in solving problems." A list of "one or two open problems" (in fact 22 of them) was given by David Cox. [2]

4. Index (statistics) - Wikipedia

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

   Sample of a well maintained data [clarification needed]. In statistics and research design, an index is a composite statistic – a measure of changes in a representative group of individual data points, or in other words, a compound measure that aggregates multiple indicators.

   where K is the number of categories, k i is the number in the i th category, d ij is the distance between the i th and i th categories, and δ is the maximum distance on the scale multiplied by the number of times it can occur in the sample. For a sample with an even number of data points

6. Seven-number summary - Wikipedia

   en.wikipedia.org/wiki/Seven-number_summary

   In descriptive statistics, the seven-number summary is a collection of seven summary statistics, and is an extension of the five-number summary. There are three similar, common forms. As with the five-number summary, it can be represented by a modified box plot, adding hatch-marks on the "whiskers" for two of the additional numbers.

7. Mathematical statistics - Wikipedia

   en.wikipedia.org/wiki/Mathematical_statistics

   inferential statistics – the part of statistics that draws conclusions from data (using some model for the data): For example, inferential statistics involves selecting a model for the data, checking whether the data fulfill the conditions of a particular model, and with quantifying the involved uncertainty (e.g. using confidence intervals).

9. Selection algorithm - Wikipedia

   en.wikipedia.org/wiki/Selection_algorithm

   Thus, a problem on elements is reduced to two recursive problems on / elements (to find the pivot) and at most / elements (after the pivot is used). The total size of these two recursive subproblems is at most 9 n / 10 {\displaystyle 9n/10} , allowing the total time to be analyzed as a geometric series adding to O ( n ) {\displaystyle O(n)} .
