Sample Statistics. 1  x refers to a sample mean. 2  s refers to the standard deviation of a sample. 3  s2 refers to the variance of a sample. 4  p refers to the proportion of sample elements that have a particular attribute. 5  q refers to the proportion of sample elements that do not have a particular attribute, so q = 1 - p.
Ecology/Environmental Response. The most basic interest of ecologists is how organisms interact with their environment. Inanimate objects do not normally interactâthey are simply acted upon by forces in the environment. Organisms, however, cannot be totally passive within a chain of events and still sustain life.
âWe therefore hold that the term âcoastal environmentâ is an environment in which the coast is a significant part or element, but clearly it is impossible to give an abstract definition which is capable of simple and ready application to any given situation.he term âcoastal environmentâ is not defined in the RMA 1991, but was interpreted by the Planning Tribunal under the previous legislation.
