    Usual, customary, and reasonable (UCR) is an American method of generating health care prices, [1] described as "more or less whatever doctors decided to charge". [2] According to Steven Schroeder , Wilbur Cohen inserted UCR into the Social Security Act of 1965 "in an unsuccessful attempt to placate the American Medical Association ". [ 3 ]

  3. List of probability distributions - Wikipedia

    en.wikipedia.org/wiki/List_of_probability...

    The normal distribution, also called the Gaussian or the bell curve. It is ubiquitous in nature and statistics due to the central limit theorem: every variable that can be modelled as a sum of many small independent, identically distributed variables with finite mean and variance is approximately normal. The normal-exponential-gamma distribution

  4. Overtime - Wikipedia

    en.wikipedia.org/wiki/Overtime

    In some other jurisdictions, such as Canada, employers might be required to pay the overtime at the higher rate (e.g. 1.5 times the normal rate), but also be allowed to require time off in lieu at the normal rate. Thus, an employee might work 48 hours in one week, and 32 hours the next week (assuming over 40 hours is overtime), and be paid an ...

  6. Normal distribution - Wikipedia

    en.wikipedia.org/wiki/Normal_distribution

    The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution. This is a special case when μ = 0 {\textstyle \mu =0} and σ 2 = 1 {\textstyle \sigma ^{2}=1} , and it is described by this probability density function (or density): φ ( z ) = e − z 2 2 2 π . {\displaystyle \varphi (z ...

    A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). [2] It is determined by collecting data from vast numbers of laboratory tests. [citation needed]

  9. Rhythm interpretation - Wikipedia

    There are 6 different sinus arrhythmia. [1] [2]A normal heart should have a normal sinus rhythm, this rhythm can be identified by a ventricular rate of 60-100 bpm, at a regular rate, with a normal PR interval (0.12 to 0.20 second) and a normal QRS complex (0.12 second and less).
