A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form.

The same relation is found for personal incomes (where it is called Pareto principle [14]), number of people watching the same TV channel, [15] notes in music, [16] cells transcriptomes, [17] [18] and more. In 1992 bioinformatician Wentian Li published a short paper [19] showing that Zipf's law emerges even in randomly generated texts. It ...
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
"The Flesch–Kincaid" (F–K) reading grade level was developed under contract to the U.S. Navy in 1975 by J. Peter Kincaid and his team. [1] Related U.S. Navy research directed by Kincaid delved into high-tech education (for example, the electronic authoring and delivery of technical information), [2] usefulness of the Flesch–Kincaid readability formula, [3] computer aids for editing tests ...
Reference counting. In computer science, reference counting is a programming technique of storing the number of references, pointers, or handles to a resource, such as an object, a block of memory, disk space, and others. In garbage collection algorithms, reference counts may be used to deallocate objects that are no longer needed.
Word, Excel, and PowerPoint on the web can all natively open, edit, and save Office Open XML files (docx, xlsx, pptx) as well as OpenDocument files (odt, ods, odp). They can also open the older Office file formats (doc, xls, ppt), but will be converted to the newer Open XML formats if the user wishes to edit them online. Other formats cannot be ...
In probability theory, the birthday problem asks for the probability that, in a set of n randomly chosen people, at least two will share a birthday. The birthday paradox refers to the counterintuitive fact that only 23 people are needed for that probability to exceed 50%. The birthday paradox is a veridical paradox: it seems wrong at first ...
