Student teams-achievement divisions (STAD) is a Cooperative learning strategy in which small groups of learners with different levels of ability work together to accomplish a shared learning goal. [1] It was devised by Robert Slavin and his associates at Johns Hopkins University.
The method below calculates the running sums method with reduced rounding errors. [18] This is a "one pass" algorithm for calculating variance of n samples without the need to store prior data during the calculation.
Cooperative learning is an educational approach which aims to organize classroom activities into academic and social learning experiences. [1] There is much more to cooperative learning than merely arranging students into groups, and it has been described as "structuring positive interdependence."
STAAD or (STAAD.Pro) is a structural analysis and design software application originally developed by Research Engineers International (REI) in 1997. In late 2005, Research Engineers International was bought by Bentley Systems.

The delta method uses second-order Taylor expansions to approximate the variance of a function of one or more random variables: see Taylor expansions for the moments of functions of random variables. For example, the approximate variance of a function of one variable is given by
Stad is the word for city or town, used in Swedish, Danish, Dutch, Afrikaans, Norwegian and Luxembourgish, and related to German Stadt. Places.
Brody and Mills [1997] argue that this population of students "could be considered the most misunderstood of all exceptionalities". [5] In each situation, the twice-exceptional student's strengths help to compensate for deficits; the deficits, on the other hand, make the child's strengths less apparent [6] although as yet there is no empirical research to confirm this theory.
