Willingness to serve, common purpose and communication are the principal elements in an organization (or cooperative system). He felt that an organization did not exist if these three

Do 95% of observations lie within 2 std dev of the mean? 4. Look at a normal probability plot—is it approximately linear? 5. Run tests of normality (such as Kolmogorov-Smirnov). But,

hal.archives-ouvertes.frStratified sampling is where the population is divided into strata (or subgroups) and a random sample is taken from each subgroup. A subgroup is a natural set of items. Subgroups might be based on company size, gender or occupation (to name but a few). Stratified sampling is often used where there is a great deal of variation within a population.
