  2. Weighted arithmetic mean - Wikipedia

    en.wikipedia.org/wiki/Weighted_arithmetic_mean

    The mean for the morning class is 80 and the mean of the afternoon class is 90. The unweighted mean of the two means is 85. However, this does not account for the difference in number of students in each class (20 versus 30); hence the value of 85 does not reflect the average student grade (independent of class).

    According to a study in France, executives and professionals are 2.6 centimetres (1.0 in) taller, and university students are 2.55 centimetres (1.0 in) taller than the national average.

  7. Class size - Wikipedia

    en.wikipedia.org/wiki/Class_size

    In general, average class size will be larger than student-teacher ratio anytime a school assigns more than one teacher to some classrooms. [2] In poor and urban districts, where schools enroll higher numbers of students needing specialized instruction, student-teacher ratios will therefore be especially imprecise measures of class size. [3]

  8. Arithmetic mean - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_mean

    A weighted average, or weighted mean, is an average in which some data points count more heavily than others in that they are given more weight in the calculation. [6] For example, the arithmetic mean of 3 {\displaystyle 3} and 5 {\displaystyle 5} is 3 + 5 2 = 4 {\displaystyle {\frac {3+5}{2}}=4} , or equivalently 3 ⋅ 1 2 + 5 ⋅ 1 2 = 4 ...
