  2. Degrees of freedom (statistics) - Wikipedia

    en.wikipedia.org/.../Degrees_of_freedom_(statistics)

    In equations, the typical symbol for degrees of freedom is ν (lowercase Greek letter nu). In text and tables, the abbreviation "d.f." is commonly used. R. A. Fisher used n to symbolize degrees of freedom but modern usage typically reserves n for sample size.

  3. Machine taper - Wikipedia

    en.wikipedia.org/wiki/Machine_taper

    The taper angle of the Morse taper varies somewhat with size but is typically 1.49 degrees (around 3 degrees included). Some modular orthopedic total hip implants use a Morse taper to mate components together. [2] Similarly, some dental implants use a Morse taper to connect components. [3]

  5. Degrees of freedom - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom

    In many scientific fields, the degrees of freedom of a system is the number of parameters of the system that may vary independently. For example, a point in the plane has two degrees of freedom for translation : its two coordinates ; a non-infinitesimal object on the plane might have additional degrees of freedoms related to its orientation .

    Random variables are usually written in upper case Roman letters, such as or and so on. Random variables, in this context, usually refer to something in words, such as "the height of a subject" for a continuous variable, or "the number of cars in the school car park" for a discrete variable, or "the colour of the next bicycle" for a categorical variable.

    Morse taper is inch-based and should be defined as such. 216.152.18.131 17:17, 3 September 2020 (UTC) I was puzzled by this, too. It appears to date nearly the creation of this article. In May 2005 DerrickOswald added the Morse taper dimensions to this article, and they were the only actual dimensions in it (the article was stubbed in March of ...

    The uppermost counterbore tools shown in the image are the same device. The smaller top item is an insert, the middle shows another three-fluted counterbore insert, assembled in the holder. The shank of this holder is a Morse taper, although there are other machine tapers that are used in the industry.
