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.
Response to Intervention (RTI) is a district-wide initiative that will be introduced at the start of the 2015-2016 school year. A core planning team, comprised of teachers and administrators, worked together last year to craft Groveport Madisonâs RTI plan. The team focused their efforts on reviewing studentsâ academic needs based on test results and resource gaps.
