Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...
The arithmetic mean can be similarly defined for vectors in multiple dimensions, not only scalar values; this is often referred to as a centroid. More generally, because the arithmetic mean is a convex combination (meaning its coefficients sum to ), it can be defined on a convex space, not only a vector space.
Most people plan to either be buried or cremated when they die, but there is another, environmentally friendly option: Human composting. "So instead of being cremated and turned into ash, you're ...
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.
