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.
Below are two tables which report the average adult human height by country or geographical region. With regard to the first table , original studies and sources should be consulted for details on methodology and the exact populations measured, surveyed, or considered.
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.
An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide.An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle, [1] but sometimes the femoral artery in the groin or another site is used.

Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [1] If the level is below 90 percent, it is considered low and called hypoxemia. [2] Arterial blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. Continued low oxygen levels may lead to ...
The most common size category. For women of about average height (5 ft 4 in) with an average bust height and an hourglass figure. Dress sizes may be given as girth at the bust in inches (e.g., 36), but even-numbered sizes from 2 to 16 are more common. Categorical sizes range from XS (extra-small) to XL (extra-large). Junior sizes
Mathematically, the normal distribution extends to negative infinity on the left and positive infinity on the right. Note, however, that only a very small proportion of individuals in a population will fall outside the −3σ to +3σ range. For example, with human heights very few people are above the +3σ height level.
