discuss the sample size relative to confidence limits and statistical emphasize the triangulation that you have incorporated in your method; emphasize how the limitations in your study and selection of key variables will preclude drawing an invalid conclusion; if applicable, rule out any [where participants change their behavior Hawthorne effect because they know they are in a study]; if applicable, rule out an the researcher selected Experimenter expectancy participants that wanted the treatment to work or had specific knowledge, skills or attitudes that do not reflect their peers in general but do align with the researcher's intentions]; and/or rule out all potential sources for in drawing invalid or inappropriate conclusions and inferences. One of the best text books available that discusses this important aspect of defending a quantitative research method as the original work of Campbell and Stanley (1963) the researchers who developed the ideas of internal and external validity. Campbell and Stanley (1963, pp. 5-6) provided a checklist of factors (extraneous variables) that could jeopardize the internal and external validity of conducting experimental and quasi-experimental research. Campbell and Stanley's eight factors jeopardizing internal validity are history, maturation, testing, instrumentation, statistical regression, biases resulting in differential selection of respondents for the comparison groups, experimental mortality, and selection-maturation interaction. Conclude this section by summarizing how your analysis counters threats to validity and ensures the study is internally valid.
