| average | <statistics> A value that represents the sum of values divided by the number of values in the set. It represents or summarises the relevant features of a set of values. Origin: M.E. Averays, loss from damage to ship or cargo, fr. It. Avaris, fr. Ar. 'awariya, damaged goods, + damage (05 Mar 2000) |

| average flow rate | <physiology> The flow rate determined by dividing the total volume passed in a time period divided by the time period, usually quoted in mls per minute. (05 Mar 2000) |
| average megawatt | <physics> One megawatt of capacity produced continuously over a period of one year. 1 MWa = 1 MW x 8760 hours/year = 8,760 Mwh = 8,760,000 kWh. Acronym: MWa (05 Dec 1998) |
| average pulse magnitude | <physics> The amplitude of pulse averaged throughout its duration; identical with peak amplitude for a square wave or pulse without droop. (05 Mar 2000) |
| law of average localization | Visceral pain is most accurately localised in the least mobile viscera and least accurately in the most mobile. (05 Mar 2000) |
| M concentration | The maximum number of bacterial cells which can be produced in a unit volume of growth medium. (05 Mar 2000) |

| peak plasma drug concentration | <pharmacology> The highest level of drug that can be obtained in the blood usually following multiple doses. (09 Oct 1997) |
| minimal alveolar concentration | The end-alveolar concentration of an inhalation anaesthetic which prevents somatic response to a painful stimulus in 50% of individuals; an index of relative potency of inhalation anaesthetics. Synonym: minimal anaesthetic concentration. (05 Mar 2000) |
