mean

Etymology: ME, mene, in the middle
occupying a position midway between two extremes of a set of values or data. The arithmetic mean is a value that is derived by dividing the total of a set of values by the number of items in the set. The geometric mean is a value between the first and last of a set of values organized in a geometric progression. Compare median, mode.

mean (x),

n a measure of central tendency that is the calculated arithmetic average of a series of scores.
mean (x) corpuscular hemoglobin,
n a measure of the weight of hemoglobin in a single red blood cell. The value is obtained by multiplying the hemoglobin value by 10 and dividing by the number of red blood cells. The normal range is between 27 and 31.
mean (x) corpuscular hemoglobin concentration (MCHC),
n a measure of red blood cells useful in identifying the type of anemia. The MCHC is obtained by multiplying the value of hemoglobin by 100 and dividing by the value of the hematocrit. The normal range is between 31.5 and 35.5.
mean (x) corpuscular volume (MCV),
n indicates the size of the red blood cells. The MCV is obtained by multiplying the hematocrit value by 10 and dividing by the number of red blood cells. The normal range is between 82 and 98.

mean deviation
the average value of a set of absolute deviations from the mean of a set of observations.
mean electrical axis (MEA)
in electrocardiography, a calculation based on the relative amplitude of Q, R and S waves in the three bipolar limb leads. It is an aid to recognizing right ventricular enlargement and various intraventricular conduction defects.
geometric mean
the antilog of the mean of the logarithm of the calculated values, the same as the nth root of the product of the values. It is often a more useful mean for growth curves.
harmonic mean
the reciprocal of the arithmetic mean of values converted to their reciprocals (used in dealing with skewed data).
