Class IntervalFrequency Less than 1520 15-2512 25-353 35-4512 More than 456 We know that to find the arithmetic mean of grouped data, we need the mid-point of every class. As evident from the table, there are two cases (less than 15 and 45 or more) where it is not possible to fi...
The figure here is a representation of the frequency distribution of a large set of laboratory values obtained by measuring a single control material. This distribution shows the shape of a normal curve. Note that a "gate" consisting of ±1SD accounts for 68% of the distribution or 68% of...
