A significant inspiration for the Wheeler-Kenyon Method came from Mortimer Wheeler’s mentor [2] Augustus Pitt Rivers. [3] Pitt Rivers was significant for his time in his use of total recording, shifting the focus away from finding ‘treasure’ and towards recording every artefact and making detailed plans and sections of the site [4] However, Bowden [5] points out that Pitt-River’s ...
Graphic breakdown of stratified random sampling. In statistics, stratified randomization is a method of sampling which first stratifies the whole study population into subgroups with same attributes or characteristics, known as strata, then followed by simple random sampling from the stratified groups, where each element within the same subgroup are selected unbiasedly during any stage of the ...

Proportionate allocation uses a sampling fraction in each of the strata that are proportional to that of the total population. For instance, if the population consists of n total individuals, m of which are male and f female (and where m + f = n), then the relative size of the two samples (x 1 = m/n males, x 2 = f/n females) should reflect this proportion.
Stratification is used in quota sampling, a non-random method in which the researcher identifies strata of the population and pre-determines how many participants are needed from each stratum. [1] This is considered a better method than convenience sampling , as it attempts to ensure different strata are properly represented.
In the MacPherson's stratified pseudomanifolds; the strata are the differences X i+i-X i between sets in the filtration. There is also a local conical condition; there must be an almost smooth atlas where locally each little open set looks like the product of two factors R n x c(L); a euclidean factor and the topological cone of a space L.
For example, events A and B are said to be collectively exhaustive if = where S is the sample space. Compare this to the concept of a set of mutually exclusive events. In such a set no more than one event can occur at a given time. (In some forms of mutual exclusion only one event can ever occur.)
Callaway now proposed a particular stratigraphic sequence of rocks (in order of the time they were originally deposited) and compared this with the sequence of strata he observed in vertical sections taken along lines at different locations and in different directions. He found that he could generally work out that some sequences were the right ...
