The average of a set of numerical values, as calculated by adding them together and dividing by the number of terms in the set.
‘The mean, or more properly the arithmetic mean, is the simple average.’
‘Consequently, means presented are geometric means and not arithmetic means.’
‘He worked on the Theory of Errors and aimed to prove that the arithmetic mean was better than a single observation.’
‘Medians were also calculated because they are less affected than arithmetic means by the extreme values often encountered in skewed distributions of dietary variables.’
‘These life table data provided the basis for calculating a selection coefficient, which we did separately for each gender, and then we used the arithmetic mean to approximate the population-wide selection coefficient.’
‘His dissertation investigates analytic functions and summation procedures by arithmetic means.’
‘It is easy to see that the medial and the binomial are closely related to the geometric mean and the arithmetic mean respectively.’
‘The quantity commonly referred to as ‘the’ mean of a set of values is the arithmetic mean… also called the average.’
‘An estimate of this total cost is obtained from data in a trial by multiplying the arithmetic mean cost in a particular treatment group by the total number of patients to be treated.’
‘Geometric means give relatively greater weight to smaller values than arithmetic means and are therefore a conservative measure of average sample size.’
‘The average may either be calculated using an arithmetic mean or a geometric mean.’
‘It is the unweighted arithmetic mean of the 15 percentages achieved by the individual member states.’
‘The median value is regarded as the average, because rare extreme morphologies influence the arithmetic mean.’
‘The geometric mean is a better estimate than the arithmetic mean of the central values, as it is less influenced by episodic high values not representative of the mean background.’
