Gasoline was once a byproduct of oil refining that later became a desirable commodity as motor fuel. The plastic used in plastic shopping bags also started as a by-product of oil refining. [1] By-products are sometimes called co-products to indicate that although they are secondary, they are desired products. For example, hides and leather may ...
Interaction effect of education and ideology on concern about sea level rise. In statistics, an interaction may arise when considering the relationship among three or more variables, and describes a situation in which the effect of one causal variable on an outcome depends on the state of a second causal variable (that is, when effects of the two causes are not additive).

A notable example is the European environmental research and innovation policy, based on the Europe 2020 strategy which will run from 2014 to 2020, [33] a multidisciplinary effort to provide safe, economically feasible, environmentally sound and socially acceptable solutions along the entire value chain of human activities.
Past studies show that microplastics — extremely small pieces of plastic that are either manufactured or a byproduct of the breakdown of larger plastic items — are not only harmful to the ...
Example 4 A hypothetical study shows a relationship between test anxiety scores and shyness scores, with a statistical r value (strength of correlation) of +.59. [15] Therefore, it may be simply concluded that shyness, in some part, causally influences test anxiety.
For example, a 2010 study published in the journal Tropical Life Sciences Research found that supplementing with tocotrienols (chemicals found in vitamin E sources) contributed to increased hair ...
Simple mediation model. The independent variable causes the mediator variable; the mediator variable causes the dependent variable. In statistics, a mediation model seeks to identify and explain the mechanism or process that underlies an observed relationship between an independent variable and a dependent variable via the inclusion of a third hypothetical variable, known as a mediator ...
