Quasi-Experimental Designs and External Validity In research the goal is to design a study that is generalizable to other populations‚ settings‚ and times‚ however this is not an easy task (Campbell & Stanley‚ 1963). Researchers try to create studies that have strong external validity‚ while attempting to avoid possible threats. External validity determines the extent to which the data collected in one study can be generalized to other populations‚ setting‚ treatments variables‚ and measurement

melting point; for annealing 800 degrees are needed. Iron‚ by comparison‚ has a melting point of 1538 degrees Celsius. Its low melting point makes copper easy to smelt‚ cast‚ and remelt without special furnaces or a heavy investment of fuel. Another advantage of copper is that it can be recycled without any loss of quality. As pure copper is too soft for structural elements or most practical appliances‚ it needs to be hardened and strengthened. It is therefore combined with
